n moles of helium gas are placed in a vessel of volume V Litre, at T K. If `V_(1)` is free volume of helium then diameter of He atom is:

The molar volume of helium is 51 .4 litre at

What is the number of helium atoms in 1 mole He?

At STP, 2 g of helium gas occupies a volume of

The pressure exerted by 12 g of an ideal gas at temperature t^(@)C in a vessel of volume V litre is 1 atm . When the temperature is increased by 10^(@)C at the same volume, the pressure increases by 10% . Calculate the temperature t and volume V . (Molecular weight of the gas is 120 ).
