The molar volume at STP(22.4 L/mol) can be used to calculate the molar mass of the gas.

If the gases have the same molar volume, the stoichiometric ratio would be one to one. Molar volume is the volume occupied by one mole of a substance. This indicates that there is a 1:1 molar ratio of each gas.

The molar volume is the ratio between the molecular mass (or atomic weight) and the density. For titanium: 47,867/4,506 = 10,6229 m3/mol

1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio

This is the ratio volume/time.

The molar volume is the ratio between molar mass and density.

Surface area to volume ratio can be calculated by taking area and dividing by volume.

Calculate the surface area = ACalculate the volume = VDivide A by V.

The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.

1. Calculate the surface area 2. Calculate the volume 3. Divide

At standard temperature and pressure, argon has a density of 1.784 grams per liter and a molar mass of 39.948 grams per mole. This gives it a molar volume of 22.4 liters.

The idea is to (1) calculate the surface area, (2) calculate the volume, (3) divide the first by the second.

The equivalent weight of a compound is the ratio between the molar mass and the valence.

Molar volume = Molar mass/Density

by condromising the the mass and diving the mass by the diameter of volume.

The volume is the ratio between the mass and density. You need the density of the material to calculate the volume.

That's not true. The molar volume of a gas is always greater than the molar volume of a liquid. I can't think of any exceptions to this.

Density is just a ratio. The ratio of the mass to the volume. e.g. 3.5g per ml.

1. You need to know the molar mass of the solute.2. Calculate the amount of the solute for 1 L: molarity x molar mass3. Calculate the amount of the solute for other volume:b(g) = V(L) x a(g) where:- b(g) is the amount of a solute in a given volume- a(g) is the amount of a solute in 1 L- V(L) is the known volume

What is the density of a cube that has a mass of 12.6 g and a measured side length of 4.1 cm

You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.

If you know the molar mass of the compound, you have to calculate the mass of the empirical formula and divide the molar mass of the compound by the mass of the empirical formula in order to find the ratio between the molecular formula and the empirical formula. Then multiply all the atoms by this ratio to find the molecular formula!

No. Specific volume is the inverse of density. Molar volume specific volume divided by mols. (i.e. g/(mLxMols)

Molal volume is another name for Atomic volume. Molar volume is the number of moles/liter (in SI units).

molarity simply means molar concentration. To calculate molar concentration, c: c = n / V where c=molar concentration (moldm-3) n=number of moles V=volume(dm3) V can also be cm3 but it needed to be converted first to dm3.
