What are two factors that determine the density of a water mass?
The answer to determine density is dividing mass by the volume. To find volume measure the area. Density = mass / volume same formula is used to determine the density of water mass as well. after calculations we come to know that density of water is 1000 kgm-3. kgm-3 ( kilogram mass raise to the power minus 3 ) is the unit of density . Density of water is a constant quantity.
Toxic chemicals in drinking water usually are reported and a safety level specified in units of parts per million ppm by mass Show how to calculate the molar concentration of arsenic in a water sam?
1 ppm means one gram of arsenic per 1,000,000 grams of water 1,000,000 grams of water is 1,000 litres = 1,000 dm^3 (one gram = one ml) assuming we have this quantity of solution: moles arsenic = mass/Mr = 1/74.9 = 0.0133511348 moles but this is for 1,000 dm^3, so for 1 dm^3 we have 1000th of this amount, which is 1.335113485 x 10^-5 moles So the molar concentration is 1.34 x 10^-5 mol.dm^-3
What is the mass of 3 cubic meters of water in kilograms?
1 cubic meter = 10 X 10 X 10 cubic decimeters. 1 cubic decimeter of water has a mass of 1 kilogram. Therefore, 1 cubic meter has a mass of 103 kilograms, or 1000 kilograms, and 3 cubic meters therefore have a mass of 3000 kilograms.
Three fifths of a mile is how many meters?
Five and three-fourths what? A foot? A yard? A rod? A mile? An Angstom?
How do you find mass if you you have volume and density?
the units of density are mass/volume so anything that gives you those variables. A scale and graduated cylinder be used if you fill the cylinder with water and the monitor the displacement of the water. 1ml of water is equal to 1 cubic cm (thats volume)
What fraction of 2m 50cm is 1m 50cm?
It is 150/250 or 3/5 in its simplest form
If you have 50 mL of water how many cm cubed do you have?
1 ml=1cm^3 so you have 50cm^3

How much does one millimeter of water weigh?
A millimetre of water weighs nothing, because a millimetre is a measurement in one dimension - a measurement of length. 3 dimensions are needed to describe a real quantity, with mass. A millilitre of water, on the other hand, equivalent to 1cm3, has a mass of exactly a gram. This is because the properties of water are among the principle constants upon which the metric system is based. A cubic millimetre of water has a mass of 0.001g.
What will be the quantity in metric ton of 384.64 cubic meter volume of furnace oil having 0.939 specific gravity?
Since the density of water is 1 MT/m3 Mass = Volume*SpGr So mass = 384.64*0.939 MT = 361.177 MT (to 3 dp)
How many feet is 50cm?
50 cm = 1.64 feet (to 3 dp)
How does concentration of salt in the ocean affect the density of water?
the concentration of the salt is more than the water so if you weigh salt and weigh water salt would weigh more.concentration is the quantity of dissolved substance per unit quantity of a solution.concentration is measured in various ways the amount of substance dissolved per unit volume of the solution (symbol c) has units of mol dm-3 or mol l-1.it is now called amount of concentration (formerly molarity).the mass concentration (symbol p)is the mass of solute per units of kg dm-3 gcm-3 ,ect.the molality is the amount of substance per unit mass solvent, commely gven in unitsof mol kg-1.
What is mass of 3 L of water?
3000 g
If a liquid has density of 2.5 g cm3 and mass of 2500 g What volume does it occupy?
With the provided quantity of mass and density the volume of liquid would be 1000cm3. density = mass / volume → volume = mass / density = 2500 g / (2.5 g/cm^3) = 1000 cm^3 = 1 litre.
What is the circumference of a circle when the radius is 50cm?
circumference = 2pi50 = 314.159 cm to 3 decimal places
What mass of sea water do you need to make 1000g when the sea water contains 3 percent by mass?
Answer % questions by relating them to actual weights/heights etc. So, if sea water contains 3% salt by mass, then 1000gms of seawater contains 30gms of salt. and 3333gm of sea water makes 99.99 gms of salt. This is worked out by salt water weight x 3 divided by 100 (3%).
