To find the mass of Cu produced in the reaction, we first need to calculate the moles of CuO reacted, and then use the stoichiometry of the reaction to find the moles of Cu produced.

Moles of CuO = 16 g / 79.55 g/mol ≈ 0.20 mol

2CuO + H2 → 2Cu + H2O

From the balanced equation, we see that 2 moles of CuO produces 2 moles of Cu.

Calculate the moles of Cu produced:
Moles of Cu = 0.20 mol CuO × 2 mol Cu / 2 mol CuO = 0.20 mol Cu

Calculate the mass of Cu produced:
Molar mass of Cu = 63.55 g/mol

Mass of Cu = 0.20 mol Cu × 63.55 g/mol = 12.71 g

Therefore, the mass of Cu produced in the reaction is approximately 12.71 grams.
