Question

The weight of 12 044 x 10^23 atoms of carbon is 4N gms, where N is?

Answer 1

6.022×10²³ atoms of carbon = 12 gm of carbon = Atomic mass of carbon

12044×10²³ atoms of carbon = (12044×10²³)/(6.022×10²³)
                                              =2000 atoms
weight = 12×2000 
           = 24000 gms

⇒4N = 24000
⇒N= 6000
