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