Question

nitrogen occurs in nature in two isotopic forms with masses 13 and 15 in the ratio of 2:1 find the average atomic mass of Nitrogen.​

Answer 1

Explanation:

Let % abundance of N-14 isotope = x <br> Then % abundance mass

= (x xx 14+(100 - x)15)/(100)

<br> Now,

(14x +(100 - x)15)/(100)=14.0067

<br> or

- x = 1400.67 - 1500 = - 99.33

or

x = 99.33

<br> Thus, % abundance of N-14 isotope = 99.33 % <br> % abundance of N-15 isotope = 0.67 %.
