The nitrogen waste calculator
A dictionary gives the mass of one molecule of each nitrogenous waste in atomic mass units, and the number of nitrogen atoms in it. You will find the share of nitrogen in each, the mass of a waste that carries a given mass of nitrogen, and the waste of an animal.
The idea. The share of nitrogen is the mass of the nitrogen atoms divided by the mass of the molecule. Use u for one nitrogen atom.
Your tasks.

nitrogen_share. It gives the per cent of nitrogen by mass in a waste. - Finish
