Dear Radha
14 g of carbon -14 atoms contains = 6.023 × 1023 atoms
1g of carbon -14 atom contains = 6.023 × 1023/14
12g of carbon -14 atom contains = (6.023 × 1023 × 12) / 14
= 5.16 × 1023
Now its 2% is (5.16 × 1023 × 2 )/100
= 10.32 × 1021
So, the number of C-14 atoms in 12 g of carbon is 10.32 × 1021
