The same amount of a metal combines with 0.20 g of oxygen and with 3.17 g of a halogen. Hence equivalent mass of halogen is

Options

A. 9
B. 35.5
C. 80
D. 127

Answer

C

Explanation

0.1 g of oxygen = 1 g of halogen,
 Hence `"equivalent mass of halogen"= (1)/(0.1) xx 8 = 80`
(Equivalent mass of O = 8)
