$28 \ g$ of $N_2$ gas occupies $10 \ L$ volume at $2.46 \ atm$ pressure. Calculate the temperature in $K$.

What is the value of the ratio of density $(d)$ to molar mass $(M)$ for an ideal gas?

The universal gas constant $R$ is defined as:

For a fixed mass of an ideal gas,the following graph is given. Determine the correct relationship between $P_1, P_2$ and $P_3$.

Which gas has a density of $1.24 \ g/L$ at $0^{\circ} C$ and $1 \ atm$ pressure?

At a given temperature,the density of gas $x$ is twice the density of gas $y$. If the molar mass of $y$ is three times the molar mass of $x$,find the ratio of their pressures $(P_x/P_y)$.
