Given that the abundance of isotopes `""^(54)Fe, ""^(56) Fe and ""(57) Fe` are 5%, 90% and 5% respectively, the atomic mass of Fe is:

A

`55.85 u`

B

`55.95 u`

C

`55.75 u`

D

`56.05 u`

Text Solution

Verified by Experts

The correct Answer is:
B
Atomic mass of `Fe = (5)/(100) xx 54 + (90)/(100) xx 56 + (5)/(100) xx 57 = 55. 95` amu
