At a certain temperature and pressure, one liter of CO2 gas weighs 1.45 g. What is the mass of one liter of C4H10 gas at the same temperature and pressure?

Answer 1

Equal volume of gases at the same T and P contain the same number of molecules (and mols).
mols CO2 = 1.45/44 = 0.03295
Then 0.03295 x molar mass C4H10 = ?

Answer 2

1.9111
