| January 10, 2021 | education
1. Let’s find the molar mass of H2:
M (H2) = 1 * 2 = 2 g / mol
2. Find the amount of substance H2, which is contained in 12 g, according to the formula:
n (H2) = m / M = 12/2 = 6 mol
3. Let’s calculate the volume of H2 according to the formula (Vm is a constant value, it is always equal to 22.4 l / mol):
V (H2) = Vm * n = 22.4 * 6 = 134.4 liters.
