The gas can be CO 2 At STP, 1 mole of any gas occupies a volume of 22.4 L. 4.4 g of a gas at STP occupies a volume of 2.24 L.Hence, the NUMBER of moles of gas = 22.42.24 =0.1 moles.0.1 moles of a gas = 4.4 g.1 mole of a gas =4.4× 0.11 =44 g.Thus, the molecular weight of gas is 44 g/mol. It is the molecular weight of CO 2 gas. |
