Metal M crystallizes into a fcc lattice with the edge length of 4.0 × 10^-8 cm. The atomic mass of the metal is \ \ \ \ g/mol. (Nearest integer)…
Metal M crystallizes into a fcc lattice with the edge length of $\displaystyle 4.0 \times 10^{-8} \mathrm{~cm}$. The atomic mass of the metal is \_\_\_\_ g/mol. (Nearest integer)
(Use : $\displaystyle \mathrm{N}_{\mathrm{A}}=6.02 \times 10^{23} \mathrm{~mol}^{-1}$, density of metal, $\displaystyle \mathrm{M}=9.03 \mathrm{~g} \mathrm{~cm}^{-3}$ )
