Sample methane gas of contains more hydrogen atoms at STP.
At STP a 22.4 liter sample of gas contains the same number of molecules as one mole.
At standard temperature and pressure 1 mol of gas occupied 22.4 liters.
Vm = 22.4 L/mol; molar volume at STP (Standard Temperature and Pressure).
V(CH4) = 1 L; volume of methane gas
n(CH4) = V(CH4) ÷ Vm.
n(CH4) = 1 L ÷ 22.4 L/mol.
n(CH4) = 0.045 mol; amount of methane
In one methane molecule, there are four hydrogen atoms.
n(H) = 4 × 0.045 mol
n(H) = 0.18 mol; amount of hydrogen atoms in 1 liter of methane
n(H2) = 1 L ÷ 22.4 L/mol.
n(H2) = 0.045 mol; amount of hydrogen molecule
In one hydrogen molecule, there are two hydrogen atoms.
n(H) = 2 × 0.045 mol
n(H) = 0.090 mol; amount of hydrogen in 1 liter of hydrogen gas
