The kinetic energy for 14 grams of nitrogen gas at 127⁰C is nearly (mol. mass of nitrogen = 28 and gas constant = 8.31 JK⁻¹mol⁻¹)

How many moles of He gas occupy 22.4 litres at 30^oC and one atmospheric pressure?

At N.T.P. the volume of a gas is found to be 273 ml. What will be the volume of this gas at 600 mm Hg and 273^∘C

A 1:1 mixture (by weight) of hydrogen and helium is enclosed in a one-litre flask at 0^∘C. Assuming ideal behaviour, the partial pressure of helium is found to be 0.42 atm, then the concentration of hydrogen would be:

3.2 g of oxygen (At. wt. = 16) and 0.2 g of hydrogen (At. wt. = 1) are placed in a 1.12L flask at 0^∘C. The total pressure of the gas mixture will be

A gaseous mixture contains 56 g of N₂​, 44 g of CO₂​ and 16 g of CH₄​. total pressure of the mixture is 720 mm of Hg. The partial pressure of methane is

The volume of 0.0168 mol of O₂​ obtained by decomposition of KClO₃​ and collected by displacement of water is 428mL at a pressure of 754 mm Hg at 25^∘C. The pressure of water vapour at 25^∘C is

The density of a gas at 27^∘C and 1 atm is ′d′. Pressure remaining constant, the temperature at which its density becomes 0.75 d is:

0.5 mole of each of H, SO₂​ and CH₄​, are kept in a container. A hole was made in the container. After 3 hours, the order of partial pressures in the container will be:

The number of moles of H₂​ in 0.224L of hydrogen gas at STP (273K,1atm) assuming ideal gas behaviour is:
