How many moles of n are in 0.203 g of n2o?

"To solve this if you find out how many mol of N2O you can multiply that by 2 to find the mol of N. There are 2 N for every one molecule of N2O.
To do this, you can use the Atomic Mass Unit of the atoms to find the mol. 1 mol of hydrogen has weights 1 gram, hydrogen has a atomic mass unit of 1."

Acovalent bond is formed between the two hydrogen bonds

The answer to the question is d
