Copper oxide can be reduced to copper by reaction with hydrogen.

CuO + H₂ → Cu + H₂O

A reaction mixture contains 1.59 g of copper oxide and 0.20 g of hydrogen.

1.27 g of copper and 0.36 g of water are made.

Calculate the number of moles of each substance to determine the limiting reactant in this reaction.
