Equivalent mass of cu

In chemistry, equivalent weight (also known as gram equivalent ) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance. The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. These values correspond to the atomic weight divided by the usual valence; for oxygen as example that is 16.0 … WebThe equivalent weight of Cu is CuO and Cu 2O (atomic wt. of Cu = 63.5) is respectively :- A 31.75, 63.5 B 63.5, 31.75 C 63.5, 63.5 D 31.75, 31.75 Medium Solution Verified by …
