Hey Friend

I am in Class 10th.And I got 96.7 percentage in class 9 and I know how to solve this question because I am preparing for NTSE and Class 10 and JEE. So your solution is Since Z=ρ×a3×NAat.wt

Z=2.73×(654×10−10)3×6.023×10^23/119

Z≈4

So your answer is 4 If my Answer is correct then you can mark me as brainlist
