How many moles of lithium oxide will form if 2.0 moles of lithium reacts?
li + o2 → li2o

1 mole Li2O

Explanation: Solution attached

First balance the given chemical equation

4 Li + O2 => 2 Li2O

The stoichiometric factor of Li and Li2O is 4 moles Li and 2 moles Li2O

Solution:

2 moles Li x 2 moles Li2O / 4 moles Li

= 1 mole Li2O
