Answer 1

Equivalent weight of an element is the weight of element which will combine with 8g of oxygen.
________________________

Weight of element = W1 g

weight of its oxide = W2 g

weight of oxygen used to combine with W1 g of the element = (W2 - W1)g

So (W2 - W1)g of oxygen combines with W1 g of the element.

1g of oxygen will combine with = W1 / (W2 - W1) g of element

8g of oxygen will combine with = [W1 / (W2 - W1)] × 8 g of element.

So equivalent weight = [ W1 / (W2 - W1) ] × 8

Answer is C.
