Two flasks of equal volumes have been joined by a narrow tube of negligible volume. Initially both flasks are at 300 K containing 0.60 mol of `O_2` gas at 0.5 atm pressure. One of the flasks is then placed in a thermostat at 600 K. Calculate number of moles of `_2`2 gas in each flask.

Two flasks of equal volume are connected by a narrow tube of negligible volume and are filled with N_(2) gas. When both the flasks are immersed in boiling water the gas pressure inside the system is 0.5 atm. Calculate the pressure of the system when one of the flasks is immersed in ice water while the other flask in boiling water.

Oxygen gas is present in a 1L flask ata pressure 7.6xx10^(-10)mm Hg at 0^(@)C . Calculate the number of O_(2) molecules in the flask.

A 2L flask contains 0.4 g O_(2) and 0.6 g H_(2) at 100^(@)C . Calculate the total pressure of the gas mixture in the flask.

At 100^(@)C a 2 litre flask contains 0.4 g of O_(2) and 0.6 g of H_(2) . What is the total pressure of this gas mixture in the flask?

A flask P contains 0.5 mole of oxygen gas. Another flask Q contains 0.4 mole of ozone gas. Which of the two flask contains greater number of oxygen atoms?

A and B are closed flasks having the same volume. In flask A, O_(2) gas is present at TK and 1 atm pressure. In flask B, H_(2) gas is present at (T)/(2)K and 1 atm pressure. If these gases behave ideally, then compare their (1) total kinetic energies, (2) total number of molecules, (3) root mean square velocities.

The volume and pressure of two moles of an ideal gas and V and p respectively Another 1mol ideal gas having volume 2V also exerts the same pressure p. Molecular mass of the second gas is 16 times that of the first gas. Compare the rms velocities of the two gases.

A vessel of volume 2000 cm^3 contains 0.1 mol of oxygen and 0.2 mol of carbon dioxide. If the temperature of the mixture is 300K. Find its pressure.

A 5 litre bulb contains n moles of nitrogen at 0.5 atm and T K, on adding 2.5xx10^(-2) mole of oxygen, it becomes necessary to cool the gas mixture to 10^oC to maintain the same pressure. Calculate n and T.
