Question

The oxide of an element contains 67.67% oxygen and the vapour density of its volatile chloride is 79. Equivalent weight of the element is:

Answer 1

100 g of the oxide will contain 67.67 g of oxygen and 32.33 g of element.

Equivalent weight of an element is its weight which reacts with 8 gm of oxygen to form oxide.

67.67 g of oxygen combines with 32.33 g of element to form oxide.

1 g of oxygen will combine with 32.3367.67 g of element to form oxide.

8 g of oxygen will combine with 8×32.3367.67=3.82 g of element to form oxide.

Hence, the equivalent weight of element is 3.82.

Answer 2

Answer:

3.82

here's the answer and hope this helps you.
