(Answer) 39.77 g of copper (II) oxide would be formed from the complete reaction of 0.500 mol Cu.
Moles of Cu reacted = 0.500 mol
According to the balanced chemical equation, the mole ratio of copper and copper (II) oxide = 1: 1
Therefore, 0.500 moles of copper (II) oxide would be formed from the complete reaction of 0.500 mol Cu.
Mass of 0.500 moles of copper (II) oxide = (Number of moles x molar mass)
= (0.500 x 79.545) g = 39.77 g.
