At $T$ $K$,an ideal gas $(Z)$ present in $V$ $L$ flask exerted a pressure of $16.4$ $atm$. Its concentration is $1$ $mol$ $L^{-1}$. What is the value of $T$ in $K$?

At $27^{\circ} C$ in a $10 \ L$ flask,$4.0 \ g$ of an ideal gaseous mixture containing $He$ (molar mass $4.0 \ g \ mol^{-1}$) and $Ne$ (molar mass $20 \ g \ mol^{-1}$) has a pressure of $1.23 \ atm$. What is the mass $\%$ of neon? $(R = 0.082 \ L \ atm \ K^{-1} \ mol^{-1})$

At constant temperature,a gas is at a pressure of $940.3 \, mm \, Hg$. The pressure at which its volume decreases by $40 \%$ is $......... \, mm \, Hg$. (Nearest Integer)

One litre of a gas weighs $2 \ g$ at $300 \ K$ and $1 \ atm$ pressure. If the pressure is made $0.75 \ atm$,at which of the following temperatures will one litre of the same gas weigh $1 \ g$?

Pressure of a mixture of $4 \ g$ of $O_2$ and $2 \ g$ of $H_2$ confined in a bulb of $1 \ L$ at $0^{\circ}C$ is $..... \ atm$

What is the relationship between the mass and volume of a gas?
