The Gas Laws

A gaseous mixture was prepared by taking equal mole of  $COand{N}_2.$ If the total pressure of the mixture was found 1 atmosphere, the partial pressure of the nitrogen  $(N_2)$ in the mixture is:

If 500ml of gas A at 400 torrs and 666.6 ml of B at 600 torrs are placed in a 3 liter flask, the pressure of the system will be

If 500ml of gas A at 400 torr and 666.6 ml of B at 600 torr are placed in a 3 litre flask, the pressure of the system will be

If $\mathrm{P}, \mathrm{V}, \mathrm{M}, \mathrm{T} \mathrm{and} \mathrm{R}$ are pressure, volume, molar mass, temperature and gas constant respectively, then for an ideal gas, the density is given by

The density of the gaseous mixture in a vessel $\left({\mathrm{N}}_2\mathrm{ }\mathrm{and}\mathrm{ }\mathrm{He}\right)$ at 2.1 atmosphere and 310 K is 1.35 g/litre. If a small pin-hole is made on the wall of the vessel, through which gases effuse, then which of the following is the correct composition of the gases He and ${\mathrm{N}}_2$   effusing out initially?

A candle is burnt in a beaker until it extinguishes itself. A sample of gaseous mixture in the beaker contains $6.08\times {10}^{20}$ molecules of ${\mathrm{N}}_2$, $0.76\times {10}^{20}$ molecules of ${\mathrm{O}}_2$, and $0.50\times {10}^{20}$ molecules of ${\mathrm{CO}}_2$. The total pressure is $734 \mathrm{mm} \mathrm{of} \mathrm{Hg}$. The partial pressure of ${\mathrm{O}}_2$ would be:

If ${\mathrm{X}}_{\mathrm{M}}, {\mathrm{X}}_{\mathrm{P}}$ and ${\mathrm{X}}_{\mathrm{V}}$ are mole fraction, pressure fraction and volume fraction, respectively, of a gaseous mixture, then

A mixture of nitrogen and water vapour is admitted to a flask that contains a solid drying agent. Immediately after admission, the pressure in the flask is $760 \mathrm{Torr}$. After standing for some hours, the pressure reaches a steady value of $745 \mathrm{Torr}$. Calculate the mole percent of water vapour in the original mixture.

A gas is heated from $273 \mathrm{K}$ to $373 \mathrm{K}$ at $1 \mathrm{atm}$ pressure. If the initial volume of the gas is $10 \mathrm{L}$, its final volume would be

If the density of a certain gas at ${30}^{\circ }\mathrm{C}$ and $768 \mathrm{Torr}$is $1.35 \mathrm{kg}/{\mathrm{m}}^3$, then density at STP is 

Air expands on heating and hence its density _____. (increases/ decreases)

For a fixed amount of gas at constant temperature, volume of a gas is _____ proportional to the pressure of a gas.
