The answer is: No.
Density is a property of a substance, and doesn't depend on the size of the sample.
Samples of different sizes all have the same density, as long as they're all samples
of the same substance, their compositions are all the same, and the conditions are
the same in every case. (Samples of ice and water have different density, because
the conditions are different.)
50 mL
If the density of the unknown is more than the density of water , it will sink If the density of the unknown is less than the density of water, it will float. Things do not float unless their densities are below that of water which is 1.00 g/ml.
You will need to expand on your questions 50g of what - lead, oil, mercury, water???? You divide the mass by the density (in common units) to get the volume then convert to the required units. i.e. for cold water density = 1000 kg/m^3 50g = 0.05kg 1m^3 = 1000 Litres = 1000000 ml. so 0.05 / 1000 * 1000000 = 0.05 * 1000 = 50ml. or another way to remember this is 1 litre of water = 1kg therefore 0.05kg water = 0.05Litres
An object will float in a substance if it is less dense that it, and if they are more they will sink. Water is 1g/mL, and most people are quite similar to this (so close that usually if someone in water breathed out, they sink, breath in, they float). What makes the difference is not how much someone weighs, but their density, which depends on how much muscle and fat they have. Fat is actually less dense than water - so having more fat will actually make a person more bouoyant. Muscle is more dense than water so a person having more muscle will sink. So a person weighing 240 pounds could float while a 160 pound person could sink - it depends on what their body is like.Because of their density: People with a lower body fat percentage (fat is less dense than water) sometimes cannot stay on the surface of the water without motion to propell themselves upwards, although most people *do* remain at the surface if they relax and lean back.Bone is considerably more dense than water, muscle is a little more dense, and fat less dense.If the weight of water you displace is less than your own weight, you will sink.
MillilLiters (mL) are units of fluid volume, the amount you would find in a cube 1 centimeter on a side. Milligrams (mg) are units of mass, or more crudely speaking, weight. The same amount of different fluids can weigh more or less, called a fluids density. Dense fluids weight more, while less dense fluids weigh less for a given volumn. Since 25 mg is a unit of mass, and mL is a unit of volume, you need to know the density. That is, 25 mg of what? I may be helpful to know that the metric standard connects mg and mL using water. 1 mL of water weighs exactly 1 gram. The density of water is 1 gram/mL, or 1 mL/gram. You can use the following formula to answer the original question, if you know the density: # of grams * # mL/gram = # of mL. If there are 25 mg, or 0.025 grams of water, this becomes .025 grams * 1 mL/gram = 0.025 mL.
depends what it is a ml of? ml of water is not as dense as ml of mercury for example
If the conditions are the same [temperature, pressure, presence or absence of dissolved substances,...] then they have the same density.
It depends on the plant.
It's not! Pure water has a density of 1.000 g/ml. Sea water has a density of 1.025 g/ml and saturated salt water has a density of roughly 1.2 g/ml.
Methylene chloride is denser than water, with a density of about 1.33 g/cm^3 compared to water's density of about 1 g/cm^3. This difference in density allows methylene chloride to separate from water in a mixture due to their immiscibility.
Which is more dense: water or helium? - Water is more dense, because water does not float like helium does. It is below air. That's why we have oceans and lakes and rivers.
To find the mass of 50 mL of water, you would multiply the volume of water (50 mL) by the density of water, which is about 1 gram per milliliter. Therefore, the mass of 50 mL of water would be approximately 50 grams.
1g=1ml so 50 ml :)
g/mL or # times more dense than water Actually, # times more dense than water is (a) called the specific gravity (not density), and (b) depends on the temperature of the water being used as a reference.
To make 400 ml of a 50% sucrose solution, you would mix 200 ml of sucrose with 200 ml of water. Measure out 200 ml of sucrose and dissolve it in 200 ml of water, ensuring the sucrose is completely dissolved to create the 50% solution.
