8.2 L of an ideal gas weights 9.0 g at 300 K and 1 atm pressure. The molecular mass of the gas is

7.00 g of a gas occupies a volume of 4.1 L at 300 K and 1 atm pressure. What is the molecular mass of the gas?

0.6 L of an ideal gas weighs 1.80 g at 27^(@)C and 1 atm pressure. Its approximate molar mass is :

7.00g of a gas occupies a volume of 4.1 litres at 300K and 1 atmosphere pressure. Calculate the molecular mass of the gas-

One litre of a gas weights 2 g at 300 K and 1 atm pressure. If the pressure is made 0.75 atm at which of the following temperature will one litre of the same gas weight one gram ?

A gaseous compound is composed of 85.7% by mass of carbon and 14.3% by mass hydrogen. Its density is 2.28 g/L at 300 K and 1 atm pressure. Determine molecular formula of the compound.

One litre of a gas weighs 2 g at 300 K and 1 atm. Pressure . If the pressure is made 0.75 atm, at which of the following temperature will one litre of the same gas weigh one gram ?
