That all depends on the type of gas and volume given for the problem. We can't determine the mass and density of the gas cylinder if we are not given these info, which can also include pressure (because density varies based on that variable).
A cubic metre of gas at normal temperature and pressure has a mass of 44.643 times the molecular weight of the gas in grams. So a cubic metre of hydrogen is 89.3 grams while a cubic metre of CO2 is 1964 grams. If the volume is 22.4 litres, the mass in grams equals the molecular weight.
