Given that the abundances of isotopes `""^(54)Fe,""^(56)Fe`, and `""^(57)Fe` are 5%, 90%, and 50 % respectively. The atomic mass of iron is :

A

55.85

B

55.95

C

55.75

D

56.05

Text Solution

Verified by Experts

The correct Answer is:
B
`""^(54)Fe to 5%`
`""^(56)Fe to 90%`
`""^(57)Fe to 5%`
Av. Atomic mass =` x_1 A_1 + x_2 A_2 + x_3 A_3`
