If the density of a gas at $NTP$ is $0.00445 \ g/mL$,then its vapor density and molecular weight are respectively:

The density of air is $0.00130 \, g/mL$. What will be the vapor density of air?

For the following equilibrium $N_2O_4 \rightleftharpoons 2NO_2$ in gaseous phase,$NO_2$ is $50\%$ of the total volume when equilibrium is set up. Hence,the percentage of dissociation of $N_2O_4$ is.......$\%$

At $STP$,the density of air is $0.001293 \ g \ mL^{-1}$. Its vapour density is $---$.

The value of $K_P$ for the equilibrium reaction ${N_2}{O_4}_{(g)} \rightleftharpoons 2N{O_2}_{(g)}$ is $2$. The percentage dissociation of ${N_2}{O_4}_{(g)}$ at a pressure of $0.5 \ atm$ is

The density of air is $0.00130 \ g/mL$. The vapour density of air will be
