Answer:

[tex]m_{Cu}=10.04gCu[/tex]

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

[tex]CuO+H_2\rightarrow H_2O+Cu[/tex]

Now, since 2.844 g of water are produced, one could compute the grams of copper considering the produced water via stoichiometry and their 1:1 molar ratio:

[tex]m_{Cu}=2.844gH_2O*\frac{1molH_2O}{18gH_2O}*\frac{1molCu}{1molH_2O}*\frac{63.546 g Cu}{1molCu}\\ \\m_{Cu}=10.04gCu[/tex]

Best regards.
