Question:

2) How many moles of Al atoms are needed to combine with 1.58 mol of O atoms to make aluminum oxide, Al2O?

HELPMESOLVETHISWITHSTEPSPLEASEEEEEEEEEEEEEEEE!!!!!!!!!! I DONT UNDERSTAND IT!!! :((((

Answer:

Balanced Equation: 2Al2 + O2 - 2Al2O Stoichiometry: (1.58molO)(2 mol Al) (1)(1molO) Moles of oxygen atoms cancel, leaving moles of aluminum atoms3.16 mol Al
Puking Pumpkin is correct, but you will spend the rest of your days trying to maintain it.
