Silver crystallises in fcc lattice. If edge length of the cell is 4.07 x 10-8cm and density is 10.5 g cm-3, calculate the atomic mass of silver.
From the equation, density = ZxM/a3 x N0, we get
M = ρ x a3 x N0/Z …………………………………1
Placing the values in equation 1,
WE GET M= 10.5 x (4.07 x10-8)3 x 6.022 x 1023/4
= 106.6 gmol-1
= Therefore, atomic mass of silver = 106.6 gmol-1
