Arsenic forms two oxides, one of which contains 65.2% and the other 75.5% of the element. Hence, equivalent masses of arsenic are in the ratio

View answer and explanation

Correct option: B

3\mathrm{ }:\mathrm{ }5

Option B (

3\mathrm{ }:\mathrm{ }5

) is correct because the equivalent mass is calculated by dividing the mass of the element by the mass of oxygen and multiplying by 8. The ratio of the equivalent masses is then simplified.
