Valence Factor of the Cu would be => 2.
Eq. weight of the Cu => molecuular mass/v.f. => 63.5/2 => 31.75  gms
This would be its eq. weight.

HELLO,
weight of the copper = 0.885gm
weight of copper oxide = 1.11g
weight of oxygen = 0.225gm
0.225gm of oxygen reacts with 0.885 gm of copper
i,e
1 gm of oxygen reacta with 0.885/0.225 gm of copper
and also,
8 gm of oxygen reacts with 0.885/0.225 X 8
                                        = 31.6gm of copper
THANK YOU
