A solid having density of 9 × 10 3 kg m –3 forms face centred cubic crystals of edge length 
pm. What is the molar mass of the solid? [Avogadro constant 
6 × 10 23 mol –1 , π 
3]
Text Solution
Verified by ExpertsThe correct answer is:
B
d = 
9 × 10 3 = 
9 × 10 3 = 
M 0 = 
= 9 × 6 × 10 –4 × 4 × 
= 0.03 kg
