Vapour density of a gas if its density is `0.178g//L` at 1atm, 273K is

The weight of 1 mole of a gas of density 0.1784 g/L at NTP is

The relative density of a gas A with respect to another gas B is 2. The vapour density of the gas B is 20, the vapour density of the gas A is:

A gas has a density of 2.68 gL^(-1) at 1 atm and 273 K. Identify it:

Calcaulate the molecular weight of HF , if density of HF gas is 3.17 g//L at 300K and 1.0 atm . Comment of the result .

A gas has a density of 1.25gL^(-1) at 1 atm and 273 K. Identify it:

At 273°C and 380 torr pressure, the density of a gas is 1.25 kg//^(3) . So its density at STP in g// is

STATEMENT-1 : Wet air is heavier than dry air. STATEMENT-2 : The density of dry air is less than the density of water at 1 atm and 273K.
