Test Preparation on Gaseous State-II-Chemistry Test Series For NEET-2020

The pressure exerted by 6.0 g of methane gas in a 0.03 m³
vessel at 129°C is (Atomic masses : C=12.01, H= 1.01 and R =
8.314 JK ^-1 mol ^-1)

A gaseous mixture was prepared by taking equal mole of CO
and N₂ . If the total pressure of the mixture was found 1
atmosphere, the partial pressure of the nitrogen (N₂) in the
mixture is

A bubble of air is underwater at temperature 15^oC and the
pressure 1.5 bar. If the bubble rises to the surface where the
temperature is 25^oC and the pressure is 1.0 bar, what will
happen to the volume of the bubble

A certain gas takes three times as long to effuse out as helium.
Its molecular mass will be

Equal masses of H₂ , O₂ and methane have been taken in a
container of volume V at temperature 27°C in identical
conditions. The ratio of the volumes of gases H₂ :O₂ :
methane would be
