MHT CET Chemistry question
Not in JEE Main or NEET syllabus
A compound CuCl has face centered cubic structure. Its density is 3.4 . The length of unit cell is (Atomic mass of Cu = 63.54 and Cl = 35.45)
Answer: (A)
Solution
M = 63.54 + 35.45 = 98.99 g/mol and z = 4, so a³ = zM/(ρN0) = 4 × 98.99/(3.4 × 6.022 × = 1.934 ×
