How many moles of cuo can be produced from 0.900 moles of Cu2O in the following reaction: 3Cu2O + O2--> 4 CuO

1.8 mol of CuO

Solution:

The balanced chemical equation is as follow,

2 Cu₂O + O₂ → 4 CuO

According to equation,

2 moles of Cu₂O produced = 4 moles of CuO

So,

0.900 moles of Cu₂O will produce = X moles of CuO

Solving for X,

X = (0.900 mol * 4 mol) : 2 mol

X = 1.8 mol of CuO
