\mathrm{P_V=n R T}

\mathrm{1 \times \frac{10}{1000}=\frac{N}{6.02 \times 10^{23}} \times .082 \times 273}

\mathrm{N=\frac{6.02 \times 10^{23} \times 10}{.082 \times 273 \times 1000}=\frac{60.2 \times 10^{23}}{21.84 \times 10^3}}

\mathrm{\mathrm{NO} \ of \ \mathrm{Cl}_2 \ molecules \Rightarrow N=2.75 \times 10^{20}}

\mathrm{\text { Hence, Number of } \mathrm{Cl} \text { Atom }=5.5 \times 10^{20}}
