1.	The isotopic abundance of C-12 and C-14 is 98% and 236 respectively What would be the sameotope in 12 carbon sample(A) 1032 10* (R) 30110 (C) S 10 (D) 602-10P
Answer» Answer: 14 g of CARBON 14 ATOM contains =6.023×1023atoms 1 g of carbon 14 atom contains =6.023×1023/14 12 g 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

Answer»

Answer:

14 g of CARBON 14 ATOM contains =6.023×1023atoms

1 g of carbon 14 atom contains =6.023×1023/14

12 g 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
