Question

Calculate the average atomic mass element X

Answer 1

39.02 amu

Step-by-step explanation:

The average atomic mass of an element can be calculated as follows :

`X=(9.67* 38+78.68* 39+11.34* 40+0.31* 41)/(100)\\\\X=(3902.29)/(100)\\\\X=39.02\ amu`

So, the atomic mass of the element X is 39.02 amu.
