## Question

### Solution

Correct option is

3 : 5

In first oxide,

Mass of arsenic = 65.2

Mass of oxygen = 34.8

Eq. mass of arsenic

In second oxide,

Mass of arsenic = 75.7 g

Mass of oxygen = 24.3 g

Eq. mass of arsenic

Eq. mass of arsenic : Eq. mass of arsenic

(oxide I)                 (oxide II)

14.99 : 24.92

or                                3 : 5
