Carbon dioxide is passed through lime water. Now, use the stoichiometry to calculate moles of H2 produced: 1 mol HCl X (3 mol H2 / 6 mol HCl) = 0.500 moles H2(g), At STP, the volume of 1 mole of gas is 22.4 L, so 0.5 mol X 22.4 L/1 mol = 11.2 L. The mass of 0.5 mol H2 would be 1.0 gram, so the density of the gas is: density = mass/volume = 1.0 g / 11.2 L = 0.089 g/L, The density of any ideal gas at STP is 1 / (22.414 L/mol) = 0.044614 mol/L, (0.044614 mol/L) x (2.01588 g H2/mol) = 0.089936 g/L H2 at STP.
