An fcc lattice has a lattice parameter `a = 400` pm. Calculater the molar volume of the lattice including all the empty space.A. 10.8 mLB. 96 mLC. 8.6 mLD. 9.6 mL

Answer» Correct Answer - D
Volume of 4 atoms `= a^(3) = (4 xx 10^(-8))^(3) cm^(3)`
volume of `N_(A)` atoms `= ((4 xx 10^(-8)))/(4) xx 6.023 xx 10^(23) = 9.6 mL`
