A mixture of 0.50 mol of `H_(2)` gas and 1.3 mol of Ar gas is in a sealed container with a volume of 4.82L. If the temperature of the mixture is `50.0^(@)C`, what is the partial pressure of `H_(2)` in the sample?

At S.T.P. 0.50 mol of H_(2) gas and 1.-0 mol of He gas

1 mol of He at 57^@C is mixed with 1 mol of Ar at 27^@C . Find the temperature of the gas mixture .

At STP, 0.50 mol H_(2) gas and 1.0 mol He gas "______________" .

A mixture of O_(2) and H_(2) gases contains 20% of H_(2) gas. At a certain temperature, the total pressure of the mixture is found to be 1 bar. What is the partial pressure of O_(2) (in bar) in the mixture?

1.00 mol of N_(2) and 3.00 mol of H_(2) are present in a container of volume 10.0 dm^(3) at 298 K. What is the total pressure of the mixture?

A gaseous mixture was prepared by taking 3 mol of H_(2) and 1 mol of CO. If the total pressure of the mixture was found 2 atmosphere then partial pressure of hydrogen (H_(2)) in the mixture is :-

A 3.0L sample of helium gas is stored in a rigid, sealed container at 25^(@)C and 1.0 atm pressure. The temperature is increased to 125%(@)C . What is the new pressure of the gas?

A mixture of a mol of C_(3) H_(8) and b mol of C_(2) H_(4) was kept is a container of V L exerts a pressure of 4.93 atm at temperature T . Mixture was burnt in presence of O_(2) to convert C_(3) H_(8) and C_(2) H_(4) into CO_(2) in the container at the same temperature. The pressure of gases after the reaction and attaining the thermal equilirium with atomsphere at temperature T was found to be 11.08 atm. The mole fraction of C_(2)H_(4) in the mixture is
