Nitrogen gas is filled in a container of volume 2.35 L at `32^@C` and 4.7 atm pressure. Calculating the number of moles of the gas.

Nitrogen gas is filled in a container of volume 2.32 L at 32^@C and 4.7 atm pressure . Calculate the number of moles of gas .

Two vessels A and B are filled with same gas where volume, temperature and pressure in vessel A is twice the volume, temperature and pressure in vessel B. Calculate the ratio of number of molecules of gas in vessel A to that in vessel B.

At pressure P and absolute temperature T a mass M of an ideal gas fills a closed container of volume V. An additional mass 2M of the same gas is added into the container and the volume is then reduced to V/3 and the temperature to T/3 . The pressure of the gas will now be:

0btain the mean free path of nitrogen molecule at 0^@C and 1.0 atm pressure. The molecular diameter of nitrogen is 324 pm (assume that the gas is ideal).

A certain mass of a gas occupies a volume of 300 c.c. at 27^(@)C and 620 mm pressure. The volume of this gas at 47^(@)C and 640 mm pressure will be "______________" .

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
