Density of a gas relative t air is `1.17`. Find the mol. Mass of the gas `[M_(air)=29g//mol]`

Density of a gas relative to air is 1.17. What is the molar mass of gas?

Vapour density of a gas, relative to air is 1.528. what is the mass of 2L of the gas at 27^(@)C temperature and 750 mm Hg pressure? [vapour density of air, relative to hydrogen=14.4]

The density of chlorine relative to air is

The vapour density of a aseous mixture of non-reactive gases 'A' and 'B' is 40. if the molar mass of gas 'A' is 20 g/mol and the mixture contains the gases in 2:3 volume ratio, then the molar mass of gas 'B' is

Density of ideal gas at 2.46 atm and 300 K is 0.8 g//L Hence g-molar mass of gas is : [R = 0.082 "L-atm/mol-K"]

At 30^(@)C and 720 mm of Hg, the density of a gas is 1.5 g// l t . Calculate molecular mass of the gas. Also find the number of molecules in 1 cc of the gas at the same temperature.
