How many grams of copper would be produced if 22.0 g of CuO react according to CuO + H2 yield Cu + H2O

Mass = 19.1 g

Explanation:

Given dа ta:

Mass of CuO = 22.0 g

Mass of copper formed = ?

Solution:

Chemical equation:

CuO + H₂ → Cu + H₂O

Number of moles of CuO:

Number of moles = mass / molar mass

Number of moles = 22.0 g / 79.545 g/mol

Number of moles = 0.3 mol

Now we will compare the moles of CuO with Cu.

CuO : Cu

1 : 1

0.3 : 0.3

Mass of copper:

Mass = number of moles * molar mass

Mass = 0.3 mol * 63.546 g/mol

Mass = 19.1 g
