The mass of a gas that occupies a volume of 612.5 ml at room temperatu

1.	The mass of a gas that occupies a volume of 612.5 ml at room temperature and pressure (25^(@)C and 1 atm pressure) is 1.1 g. The molar mass of the gas is
Answer» 66.25 G `mol^(-1)` 44 g `mol^(-1)` 24.5 g `mol^(-1)` 662.5 g `mol^(-1)` Solution :No. of moles of a gas that occupies a volume of 612.5 ml at room temperature and PRESSURE (`25^(@)`C and 1 atm pressure) `612xx10^(-3)L//24.5molL^(-1)` 0.025moles We know that, Molar mass=Mass no. /no. of moles 1.1g/0.025 mol=44g `mol^(-1)`
