A vessel of volume V contains n1 moles of oxygen and n2 moles of carbon dioxide at absolute temperature T. The pressure of the mixture is
An enclosure of volume V contains a mixture of 8g of oxygen, 14g of nitrogen and 22g of carbon dioxide at absolute temperature T. The pressure of the mixture of gases is (R is universal gas constant)
A vessel of volume V contains an ideal gas at absolute temperature T and pressure P. The gas is allowed to leak till its pressure falls to P. Assuming that the temperature remains constant during leakage, the number of moles of the gas that have leaked is
