Divide the oxygen-16 mass by 1.06632

Explanation:

It may be helpful to look at this algebraically.

Let the mass of nitrogen-15 = x

As the mass of nitrogen -15 is 1.06632 times bigger than the mass of oxygen-16:
1.06632 xx x = 15.9949

Now you just rearrange to calculate x:
15.9949/1.06632 = x

So the mass of nitrogen-15 is:
x = 15.0001

Hope that helps
