Problem
A steel gas cylinder of volume 5L has a mass of 2.50kg when empty. When filled with an unknown gas at room conditions, its mass becomes 2.57kg.
(i) Calculate the mass of the gas contained in the cylinder.
(ii) Convert the volume of the cylinder to m3.
(iii) Determine the density of the unknown gas in kgm−3.
(iv) The density of air at the same conditions is approximately 1.29kgm−3. Is the unknown gas lighter or heavier than air? State your reason based on the value obtained in part (iii).
