Answer:
It's 3-Methylhexane.
Explanation:
The only way I can explain this is to say you need to draw out the Lewis structure and find out what it is. Or if they don't give you the composition of the molecules then you'll have to memorize the structures.
Let x = % abundance 63Cu
<span>let y = % abundance 65Cu </span>
<span>x +y = 100 </span>
<span>y = 100-x </span>
<span>63.546 = [ 62.9396 x + 64.9278 ( 100-x) ] / 100 </span>
<span>6354.6 = 62.9396 x + 6492.78 - 64.9278 x </span>
<span>138.18 = 1.9882 x </span>
<span>x = 69.50 % </span>
<span>y = 100 - 69.50 = 30.50 %</span>
