45.37

Text Solution

Verified by Experts

The correct Answer is:
C
` underset(0.189 g)("Organic")` compound ` to ` Comp. + `underset(0.287 g ) (AgCl ) `
Percentage of chlorine in AgCl = ` (35.5 ) /( 143.35 ) xx 100 `
` = 24.76 % `
Weight of chlorine in 0.287 g AgCl ` = ( 24.76 ) / (100) xx 0.287 `
` = .07106 g `
Percentage of chlorine in 0.189 g = ` ( .07106 ) /( 0.189 ) xx 100 `
` = 37.598 % `
