Question

Calculate the mass percent of benzene and carbon tetrachloride. If

22 gram of benzene is dissolved in 122 gram of carbon

tetrachloride. (Molar mass of carbon tetrachloride = 142 and Molar

mass of benzene = 78)​

Answer 1

Explanation:

total mass of solution= 22+122=144

mass percent of benzene= 22/144 x 100= 15.3%

mass percent of ccl4= 122/144x100= 84.72%
