Equivalents!

Chemistry Level 1

If x x grams of a metal gives y y grams of its oxide, the equivalent mass of the metal (in grams) is __________ . \text{\_\_\_\_\_\_\_\_\_\_}.

8 x y − x \dfrac{8x}{y-x} 8 y y − x \dfrac{8y}{y-x} 8 y x \dfrac{8y}{x} 8 x y \dfrac{8x}{y}

Here amount of metal in y gms of metallic oxide is x gms

So amount of oxygen in y gms of oxide is (y-x) gms

We know that equivalent weight of oxygen is 8

Now

(y-x) gms of oxygen react with x gms of metal

Therefore 8 gms of oxygen react with 8x/(y-x) gms of metal.

Therefore equivalent weight of metal is 8x/(y-x)
