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 data:

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
