The weight of $1$ mole of a gas of density $0·1784 \mathrm{g}/\mathrm{L}$ at NTP is

The number of $\mathrm{HCl}$ molecules present in $10 \mathrm{mL}$ of $0.1 \mathrm{N}$ $\mathrm{HCl}$ solution is:

(Hint: $\mathrm{Normality}=\mathrm{n}-\mathrm{factor}\times \mathrm{molarity}$)

The number of atoms in $12 \mathrm{g}$ of ${}_6{}^{12}\mathrm{C}$ is:

$5$ moles of a gas in a closed vessel was heated from $300 \mathrm{K}$ to $600 \mathrm{K}$. The pressure of the gas doubled. The number of moles of the gas will be
