b (b) Vander wall's gas equation for ? mole of real gas
on comparing the given equation with this standard equation we get $\mu = \frac{1}{2}$. Hence $\mu = \frac{m}{M}$==> mass of gas $m = \mu m = \frac{1}{2} \times 44 = 22gm.$

$310\,J$ of heat is required to raise the temperature of $2\,moles$ of an ideal gas at constant pressure from $25\,^oC$ to $35\,^oC$ . The amount of heat required to raise the temperature of the gas through the same range at constant volume is .... $J$
When $2 \,\,gms$ of a gas are introduced into an evacuated flask kept at $25\,^0C$ the pressure is found to be one atmosphere. If $3 \,\,gms$ of another gas added to the same flask the pressure becomes $1.5$ atmospheres. The ratio of the molecular weights of these gases will be
The temperature of a gas having $2.0 \times 10^{25}$ molecules per cubic meter at $1.38 \mathrm{~atm}$ (Given, $\mathrm{k}=$ $\left.1.38 \times 10^{-23} \mathrm{JK}^{-1}\right)$ is :
Five moles of helium are mixed with two moles of hydrogen to form a mixture. Take molar mass of helium $M_1=4\ g$ and that of hydrogen $M_2=2\ g$ The equivalent molar mass of the mixture is
One mole of an ideal gas $\left( {\frac{{{C_P}}}{{{C_V}}}\, = \gamma } \right)$ heated by law $P=\alpha V$ where $P$ is pressure of gas, $V$ is volume, $\alpha$ is a constant what is the heat capacity of gas in the process-
In the isothermal expansion of $10\,g$ of gas from volume $V$ to $2V$ the work done by the gas is $575\,J$. What is the root mean square speed of the molecules of the gas at that temperature ..... $m/s$?
In kinetic theory of gases, a molecule of mass m of an ideal gas collides with a wall of vessel with velocity $V.$ The change in the linear momentum of the molecule is
