Question

What is the number of unit cells in 10 g NaCl ?
plz do give a good explanation with your answer
​

Answer 1

Hey, Dear

● Answer -

10 gm of NaCl contains 2.57×10^22 unit cells

● Explanation -

NaCl crystallizes in CCP lattice with Z = 4.

Number of molecules are calculated by -

N = No.W / Z.M

N = (6.022×10^23 × 10) / (4 × 58.5)

N = 2.57×10^22 molecules

Hence, 10 gm of NaCl contains 2.57×10^22 unit cells.

Hope this helps you.
