A pure sample of cobalt chloride weighting `1.30 g` was found to contains `0.59 g` cobalt and `0.71 g` chloride on quantitative analysis. What is the percentage composition of cobalt chloride?

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
a. `1.30 g` of the compound `= 0.59 g of Co`
`100 g` of compound `= (0.59 xx 100)/(1.3) = 45.4%`
b. `1.30 g` of the compound `= 0.71 g` of chloride
`100 g` of the compound `= (0.71 xx 100)/(1.3) = 54.6%`
