Chlorine has two naturally occuring isotopes, `""^(35)Cl " and " ""^(37)Cl`. If the atomi mass of Cl is 35.45, the ratio of natural abundance of `""^(35)Cl " and " ""^(37)Cl` is closest to

Text Solution

Verified by Experts

Let fraction of `""^(35)C =x, therefore` Fraction of `""^(37)C=1-x`
`therefore` Atomic mass = x(35) + (1.0-x)37 = 35.45
`therefore x= 0.775`
`therefore ""^(35)Cl = 77.5%` and `""^(37)Cl = 22.5%`
