Number of atoms $=\frac{\mathrm{w}}{\mathrm{ }\mathrm{molar}\mathrm{ }\mathrm{mass}\mathrm{ }}\times {\mathrm{N}}_{\mathrm{A}}\times \mathrm{atomicity}$

Number of atoms in $1\mathrm{g}$ of $\mathrm{Li}\left(\mathrm{s}\right)$ = $\frac{1}{7}\times {\mathrm{N}}_{\mathrm{A}}\times 1$

Number of atoms $1\mathrm{g}$ of $\mathrm{Ag}$$\left(\mathrm{s}\right)$ =$\frac{1}{108}\times {\mathrm{N}}_{\mathrm{A}}\times 1$

Number of atoms $1\mathrm{g}$ of $\mathrm{Mg}\left(\mathrm{s}\right)$ = $\frac{1}{24}\times {\mathrm{N}}_{\mathrm{A}}\times 1$

Number of atoms $1\mathrm{g}$ of ${\mathrm{O}}_2\left(\mathrm{g}\right)$ = $\frac{1}{32}\times {\mathrm{N}}_{\mathrm{A}}\times 2$
