| August 7, 2021 | education
The mass of a certain volume of gas can be determined using the concept of the amount of a substance.
we know that 1 mole of any gas occupies a volume of 22.4 liters
1. find the amount of substance 5.6 liters of hydrogen
5.6 L: 22.4 L / mol = 0.25 mol
2. find the molar mass of hydrogen H2
M (H2) = 1 * 2 = 2g / mol
3. Find the mass of 0.25 mol of hydrogen
0.25 mol * 2 g / mol = 0.5 g.
