0.3780g of an organic chloro compound gave 0.5740g of silver chloride. Calculate the percentage of chlorine in the compound.

Explanation

In this problem, Mass of the organic compound= 0.3780g Molecular mass of AgCl= 108+ 35.5 = 143.5
`because` 143.5g of AgCl contain chlorine= 35.5g
`therefore` 0.5740g of AgCl will contain chlorine= `(35.5)/(143.5) xx 0.5740= 0.132g`
`therefore` Percentage of chlorine in the given compound `=(0.142)/(0.3780)xx 100= 37.57`
