Homework Equations
Mole calculations
The Attempt at a Solution
First find the amount of moles of Oxygen in sugar. Multiply 12.6g by 96grams O/ 180grams sugar to get 6.72grams of sugar. The divide 6.72grams by 16 to get 0.42 moles of Oxygen. Then I'm struggling at the next part. To get the same amount of moles of Nitrogen shouldn't I just divide 0.42 by 3 to get 0.14? 0.14 was not the correct response on mastering chem.
