Let us find the number of moles by the formula v = V / 22.4, where v is the amount of substance, V is the volume of the substance, 22.4 l / mol is the molar volume of gases.

v = 6.72 / 22.4 = 0.3 mol.

Let us find the mass of methane by the formula m = Mr * v, where m is the mass of the substance, Mr is the molecular mass.

Mr (CH4) = 16 g / mol.

m (CH4) = 16 * 0.3 = 4.8 g

Answer: 6.72 liters of methane weigh 4.8 g.
