Metal M crystallizes into a fcc lattice with the edge length \( 4.0 \times 10^{-8} \, \text{cm} \). The atomic mass of the metal is ________ \( \text{g/mol} \). (Nearest integer)
(Use: \( N_A = 6.02 \times 10^{23} \, \text{mol}^{-1} \), density of metal, \( M = 9.03 \, \text{g} \, \text{cm}^{-3} \))
