A copper complex crystallising in a CCP lattice with a cell edge of $\displaystyle 0.4518$ nm has been revealed by employing $\displaystyle X$-ray diffraction studies. The density of a copper complex is found to be $\displaystyle 7.62 \mathrm{~g} \mathrm{~cm}^{-3}$. The molar mass of copper complex is \_\_\_\_ $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$. (Nearest integer) [Given : $\displaystyle \mathrm{N}_{\mathrm{A}}=6.022 \times 10^{23} \mathrm{~mol}^{-1}$ ]
