In Carius method of estimation of halogen, 0.15 g of an organic compound gave 0.12 g of AgBr. Find out the percentage of bromine in the compound.

Explanation

Molar mass of `Ag Br = 108 + 80 = 188 g mol ^(-1)`
188 g Ag Br contains 80 g bromine
`0.12 g Ag Br ` contains `( 80 xx 0.12)/(188) g ` bromine
Percentage of bromine `= (80 xx 0.12 xx 100)/(188 xx 0. 15) = 34. 04 %`
