    W = (w2 - w1) grams
    Ew=[w2 / (w2 - w1)] * atomic weight of oxygen

    Oxide refers to a binary compound of oxygen with a more electropositive element or group. Oxide refers to chemical compound containing oxygen and one other chemical element. Oxides are widely and abundantly distributed in nature. Water is the oxide of hydrogen. Silicon dioxide is the major component of sand and quartz. Carbon dioxide is given off during respiration by animals and plants.

    Any of a large and important class of chemical compounds in which oxygen is combined with another element is oxide. Metal oxides contain a metal cation and the oxide anion (O2-); they typically react with water to form bases or with acids to form salts. Oxides of nonmetallic elements are volatile compounds in which a covalent bond joins the oxygen and the nonmetal; they react with water to form acids or with bases to form salts.

    Calculate the equivalent weight of oxygen.
    Weight of metal oxide (w2) (grams) = 25
    Weight of metal (w1) (grams) = 20

    Apply Formula:
    W = (w2 - w1) grams
    Ew=[w2 / (w2 - w1)] * atomic weight of oxygen
    Weight of oxygen (W) = 5

    Equivalent weight (Ew) = 40
