The molecular weight of a gas is `45`. Its density at STP is

The molecular weight of a gas is 44. The volume occupied at STP by 2.2 g of the gas would be

If the molecular weight of a gas be 16-its vapur density to

If 'v' is the velocity of sound in a gas , then 'v' is directly proportional to (here M , d and T represents molecular weight of gas , density of gas and its temperature , respectively.)

The molecular weight of a gas that diffuses twice as rapidly as a gas with molecular weight 64, is

Molecular mass of a gas is 78 . Its density at 98 ^(@)C and 1 atm will be

Molecular mass of a gas is 78 . Its density at 98 .^(@)C and 1 atm will be

The density of gas A is twice that of B at the same temperature the molecular weight of gas B is twice that of A. The ratio of pressure of gas A and B will be :

The density of gas A is twice that of B at the same temperature the molecular weight of gas B is twice that of A. The ratio of pressure of gas A and B will be :

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
