-BARSIC- [3]

Answer:

Mass of copper oxide: 10g

Mass of copper: 8.882g

Mass of oxygen: 1.118g

                                                                <u> Cu</u>               <u>O</u>

                                                              8.882           1.118

Divide by A_{r}                                   8.882÷63.5       1.118÷16

                                                               0.14             0.07

Divide by the lowest number          0.14/0.07       0.07/0.07

                                                                  2                  1

Check the ratio now, Cu has 2 atoms and O has 1 atom .

The formula is Cu_{2} O
