i meant to type 680 kg/m cubed

1 m^3 = 1000 litres
4 litres = 0.004 m^3
mass = density*volume = 680*0.004 = 2.72 kg

mass of the gas = m = rho V; where rho is the mass density = 680 kg/m^3 and V is the volume of the 4 L gas can. A liter is 1,000 cm^3 by definition. That's 10 cm X 10 cm X 10 cm, or .1 m X .1 m X .1 m = .001 m^3
Thus, 4 L = .004 m^3; so that m = rho V = 680 X .004 = 2.72 kg.

Well, a liter is 0.001 cubic meters, so 4 liters is 0.004 cubic meters. 0.004 cu.m. x 680 kg./cu.m. = 2.72 kg. of gasoline.

The S.G. of the gas is therefore 0.680.
4 litres of water = 4kg
4 x 0.68 = 2.72kg of gas
