The Equivalent weight of a substance depends upon the nature of chemical reaction in which the substance takes part. It has the dimensions and units of mass, unlike atomic weight, which is dimensionless. The oxide refers to a binary compound of oxygen with a more electropositive element or group. Make use of this oxide calculator to determine the equivalent weight of oxygen. Enter the weight of metal oxide and metal in the below calculator to find the weight of oxygen atoms and the metal weight.
Calculate the equivalent weight of oxygen.
Weight of metal oxide (w2) (grams) = 45
Weight of metal (w1) (grams) = 25
Weight of oxygen (W) = 20
Equivalent weight (Ew) = 18 .
