1. The problem statement, all variables and given/known data When a problem says 76 moles of P4O10 contains how many moles of P. I can't seem to see why 76 moles of this molecule would contain more moles in it. 2. Relevant equations 3. The attempt at a solution I know the answer is 76 moles of P = 76 * 4 but how could a compound P4O10 that has 76 moles have 76 moles of P and 76 moles of O. in my head thats like saying 25 lb back of wine bottles is 25 lb of wine + 25 lb of bottles. Can anyone help me fix this brain dump?
