The volume of the 12.96 g sample of pure hydrogen gas is 145.24 L

How to determine the mole of hydrogen gas

We'll begin by calculating the number of mole in 12.96 g hydrogen gas. This can be obtained as follow:

  • Mass of Hydrogen gas = 12.96 g
  • Molar mass of hydrogen gas = 2 g/mol
  • Mole of Hydrogen gas =?

Mole = mass / molar mass

Mole of Hydrogen gas = 12.96 / 2

Mole of Hydrogen gas = 6.48 mole

How to determine volume of hydrogen gas

To determine the volume of the pure hydrogen gas, we shall assume that the gas is at standard temperature and pressure (STP). Thus, we shall apply the ideal gas equation as illustrated below:

  • Temperature (T) = STP = 273 K
  • Pressure (P) = STP = 1 atm
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Number of mole (n) = 6.48 mole
  • Volume (V) =?

V = nRT / P

V = (6.48 × 0.0821 × 273) / 1

V = 145.24 L
