At same temperature and pressure,the fraction of masses having equal volumes of `O_2` and `SO_3` gas is

Equal masses of the two gases A and B are kept in two separate vessels at the same temperature and pressure. If the ratio of the molecular masses of A and B is 2 : 3 , find the ratio of the volumes of the two vessels.

At a given volume and temperature the pressure of a gas

A mixture of two gases A and B in the mole ratio 2:3 is kept in a 2 litre vessel. A second 3 litre vessel has the same two gases in the mole ratio 3:5 . Both gas mixtures have the same temperature and same pressure. They are allowed to intermix and the final temperature and pressure are the same as the initial values, the final volume beingh 5 litres. Given theat the molar masses are M_(A) and M_(B) . what is the mean molar mass of the final mixture :

A gas is filled in a vessel at a certain temperature and pressure. At the same temperature more gas is filled in the vessel so that its mass increased by 40%. Calculate the ratio of initial and final pressures.

A gas is filled in a vessel at a certain temperature and pressure. At the same temperature more gas is filled in the vessel so that its mass increases by 40%. Calculate the ratio of initial and finial pressures.

60ml of mixture of equal volumes of Cl_(2) and an oxide of chlorine, i.e., Cl_(2)O_(n) was heated and then cooled back to the original temperature. The resulting gas mixture was found to have volume of 75ml . On treatment with KOH solution, the volume contracted to 15ml . Assume that all measurements are made at the same temperature and pressure. Deduce the value of n in Cl_(2)O_(n) . The oxide of Cl_(2) n heating decomposes quantiatively to O_(2) and Cl_(2) .

In a Regnault's experiment, the mass of a definite volume of a gas was found to be 4.6420 g, whereas the mass of the same volume of hydrogen at the same temperature and pressure was found to be 0.2902 g. Calculate the vapour density and molecular mass of the gas.

1.40L of an unknown gas requires 57 second to diffuse and the same volume of N_(2) gas takes 84 second to diffuse at the same temperature and pressure. What is the molecular mass of the unknown gas?

A closed vessel A having volume V contains N_(2) at pressure P and temperature T. another closed vessel B having the same volume V contains. He at the same pressure P. but temperature 2T. The ratio of masses of N_(2) and He in the vesses A and B is

A vessel contains 1 mole of O_2 gas (relative molar mass 32) at a temperature T. The pressure of the gas is P. An identical vessel containing one mole of He gas (relative molar mass 4) at temperature 2T has a pressure of
