Question

When a metal is burned its weight is increased by 24 the equivalent weight of the metal will be?

Answer 1

Answer:

"Equivalent weight of O^2-(oxide) ion is : Molar mass of oxygen/ charge of oxygen

= 16 g mol^-1 /2 mol eq^-1

= 8 g eq^-1

Let us consider M to be the equivalent weight of the metal.

Therefore when M grams of the metal will react with 8g of oxygen the corresponding metal oxide formed will be 8gm more in Mass. This 8 gram is 24% of M.

Or we can say that M x 24/100 = 8 gram

So, M = 100 x 8/24 = 33.33 g
