35 meters equals how may kilometers?
1000 metres = 1 kilometre 140 metres = 140/1000 = 0.14 kilometres
How many grams are in one ounce?
There are approximately 28.35 gm (grams) of the metric system in one oz (ounce) of the British Imperial and US Standards for weights and measures.Here's a formula for you to use:1 oz=28.34952313 g1 avoirdupois ounce = 28.35 gm1 troy ounce = 31.10 gm (Troy ounces are used for weighing gold, and other precious metals.)1 ounce = 28.34952 gramsIn this context, "ounce" means the unit of mass, not "fluid ounce", which is a unit of volume (typically of a liquid).
Is salt water more dense then tap water?
Yes. The ocean is about 2.5% denser than fresh water. This causes greater buoyancy of objects and a swimmer can notice this easily. The average density of water at the ocean's surface is about 1.025 g/ml or 2.5 % greater than pure water. This is due to the mass of added sea salts which is 3.5% or .035 g/ml. The added sea salts have only a small effect on the volume, so the resulting combination is more dense than pure water. If the salt added to water caused the volume to increase significantly, then the resultant combination could be less dense, but it is not. All of this is true for sea water as well as plain salt water which has only pure NaCl added. In approximate terms, this is true for dissolving ionic substances in water, but one does have to start taking into account how large the molecule are being dissolved and their mass which becomes the primary factor with large molecules.
Why is salt water more dense than regular water?
Density is a unit of measurement defined by how much matter takes up a certain amount of volume or space, therefore, when salt is added to water the following occurs:A) The volume or space that the water takes up has very slightly increased butB) The mass of the water has very greatly increased due to the salt ions (Ions being atoms with either extra electrons or missing electrons) having been attracted to the water and bonded themselves very closely to the water molecules.The mass of the water has increased faster than the volume or space that it requires to take up, therefore the density of the water with salt in it is greater than normal water because for a certain volume of water there is more material or matter in salt water than there is in the same volume of normal water. So basically, in the very simplest answer would be "Because there's more stuff than just water in it." And most of that other "stuff" is heavier than pure water.If you need something visual, picture (or try) this: You have 2 glasses filled with the same amount (volume) of freshwater. They both have the same density. Now, to one of the units, add 25 grams of table salt and stir it until it is all dissolved. Once dissolved, you will find that the volume of this unit is still the same (one unit) but if you weigh it, it is now 25 grams heavier than the remaining freshwater sample. Therefore the unit with the salt is now denser than the freshwater unit.(Basically, think of fresh water as marbles in a cup. There are gaps between the marbles. When you add salt, the gaps are filled in, making it denser.)Need something more scientific than just "because there's more stuff, it's heavier"? Check out what this science teacher has to say:Firstly, you need to understand that when salt (sodium chloride NaCl) is added to water it disassociates into two charged ions; Na+ and Cl-The water molecule is shaped much like this:O/ \H HThe oxygen has two lone pairs of electrons exposed on the top, so it attracts anything positive (e.g. Na+). The Hydrogen atoms are sharing their one electron with each of the covalent bonds with the oxygen atom. This exposes the positively charged nucleus and attracts negatively charged particles (e.g. Cl-).This has the overall effect of pulling the water molecules closer together (but not chemically bonding) in salt water than they would normally be in fresh water. We define density as being related to the number and size of particles in a given volume. The overall pulling together of the water molecules means that more water molecules will fit into a smaller space.
Which water will hold up an heavy object longer salt water or tap?
Salt water weighs more than fresh water by 2.5%. Yes. Salt water from the ocean weighs approx 8.55 lbs per gallon and fresh water weighs approx. 8.34 lbs per gallon, so that is 2.5% greater density of ocean water.This is approximate because the more salt dissolved in the water the more it will weigh. (For example water from the Dead Sea would weigh more than ocean water) Also, as water gets colder its density increases until it is 4 degrees centigrade above freezing, at which point it begins to expand and then expands abruptly when it forms ice. The salt concentration affect freezing temperature and temperature effects density, so the 2.5% greater density is reliable only for the middle temperature range, away from freezing and boiling.When one solute (the substance getting dissolved) dissolves in a solvent (the substance doing the dissolving) the solute fills in the spaces between the molecules. (Yes, it's true. There is actually space between molecules. If you would like to prove that to yourself, mix exactly 50 milliliters of water with 50 milliliters of rubbing alcohol and see how much you get. It's cool!!) (Lest you think this is always true, there are other examples of mixing two liquids which result in an increase in volume. That requires a more detailed explanation.)When salt (the solute) dissolves in water (the Solvent), the ions of sodium separate from the ions of chlorine and enter the spaces between the water molecules. In this process, the salt adds to the mass of the solution but the volume added is less than the volume of the original salt. To be specific, if you added one cubic centimeter of salt to a liter of water, you would find the water increased in volume only about a half of a cubic centimeter. Since a cubic centimeter of salt weighs more than a cubic centimeter of water, the density of the salt water has increased.So, salt water does weigh more than fresh water. The most amazing thing is that this difference in weight, more accurately the density, drives the largest ocean current in the world called the Thermohaline Conveyor. It's pretty cool.
How many pounds in 400 grams ground beef?
There is .035 grams in an ounce. 400 grams is approximately one pound.
How many grams in 2.37 pounds?
First take the weight in pounds and multiply it by 453.59. The resulting number is the weight in grams. In this case the answer is 1215.64 grams.

.035 g
3500 grams equals how many kilograms?
3500 milligrams = 350 centigrams = 35 decigrams = 3.5 grams = .35 dekagrams = .035 hectograms = .0035 kilograms
35 milligrams is how many grams?
Here you have to divide by 1000. 35/1000 will give you 0.035 grams
What is the approximate number of grams of milk fat in a 200-gram serving of fat milk which is 3.5 percent?
First of all, you need to change the 3.5% to a decimal which is .035. Then you need to multiply .035 by 200 and you will get 7. So the answer for this math homework is 7.
