67. Pure bromobenzene, C H Br, boils at 156.0°C and has a boiling point constant of 6.26°C/m. A sample of bromo benzene is contaminated by anthracene, C4H10. The boiling point of the impure sample is 159.2°C. How pure is the sample? (Express your answer as mass percent bromobenzene.) I've spent forever trying to figure this out. For now my answer is 6.56%, but it doesn't seem right. Before, I got 97.9%. are either of those correct?
