One mole of an ideal gas has a capacity of 22.710947(13) litres at standard temperature and pressure (a temperature of 273.15 K and an absolute pressure of exactly 105 Pa) as defined by IUPAC since 1982.

At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas. Or you could think about the problem a bit and use PV=nRT.

Avagadro's constant states that in every 1 mole of any substance that is in existence, has exactly 6.022 × 10²³ molecules or atoms. That means there are 1.50575 x 10²³ hydrogen molecules in 1 g of hydrogen gas. Therefore 1g of H₂ gas has more molecules than 1 g of methane gas.

The van der Waals equation of state approaches the ideal gas law PV=nRT as the values of these constants approach zero. The constant a provides a correction for the intermolecular forces. Constant b is a correction for finite molecular size and its value is the volume of one mole of the atoms or molecules.

Calculate the number of moles of gas from the given pressure, volume, and temperature. n = 0.0371245 mol. The molecular weight of the gas is grams of gas (1.56 g) divided by moles of gas: 1.56 g ÷ 0.0371245 mol = 42.020768 g/mol.

You can calculate the number of molecules from moles by using Avogadro's constant, 6.02×1023 molecules/mol .

The equation is fairly simple. The number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole.

Avogadro's Law is stated mathematically as follows: Vn=k, where V is the volume of the gas, n is the number of moles of the gas, and k is a proportionality constant.

The formula for escape velocity comprises of a constant, G, which we refer to as the universal gravitational constant. The value of it is = 6.673 × 10-11 N . m2 / kg2. The unit for escape velocity is meters per second (m/s).

2 The semi-empirical mass formula. We saw the binding energy can be expressed as. BE = avA − asA2/3. where av (the volume term constant) and as (the surface term constant) are parameters to be determined from data.
