Pure hydrogen sulphide is stored in a tank of $100 \, L$ capacity at $20 \, ^oC$ and $2 \, atm$ pressure. The mass of the gas will be ............... $g$.

Three bulbs are filled with $CH_4$,$CO_2$,and $Ne$ as shown in the picture. The bulbs are connected through pipes of zero volume. When the stopcocks are opened and the temperature is kept constant throughout,the pressure of the system is found to be $...... \ atm$. (Nearest integer)

At $300 \ K$,the following graph is obtained for one mole of an ideal gas. If its pressure is $10 \ atm$,then its volume (in $L$) will be

Which of the following equations is true for $8.8 \times 10^{-2} \ kg$ of carbon dioxide gas?

Two separate bulbs contain ideal gases $A$ and $B$. The density of gas $A$ is $4$ times that of gas $B$. The molecular mass of $A$ is half that of gas $B$. The two gases are at the same temperature. The ratio of the pressure of $A$ to that of gas $B$ is

The density of oxygen gas at $1.0 \, atm$ pressure and $27 \, ^oC$ temperature is ............. $g/L$.
