1) First let's calculate the molar mass of O₂ and H₂:O₂: (16x2) = 32 g/mol (for both oxygen 1 and 2)H₂: (1x2) = 2 g/mol2) Now let's calculate the mass of gas sample (g) of:Oxygen 1: mass = mole x molar massmass = 1 x 32 = 32 gMass of Oxygen 1: 32 gOxygen 2:mass = mole x molar massmass = 2 x 32 = 64 gMass of Oxygen 2: 64 gHydrogen: mass = mole x molar massmass = 1 x 2 = 2 gMass of Hydrogen: 2 g For the two oxygen samples, if the number of moles double, the mass double and the volume also double.But the two gases of the same volume have different masses (Hydrogen 2 g and oxygen 32 g). So there is no relationship between volume and mass for different gases.
