The boiling point of pure benzene (C6H6; Mm=78.0g/mol; kb=2.53 degrees celsius/m; p=.877g/mL) is 80.1 degrees celsius. What mass of vanillin (Mm=152.1 g/mol; non-electrolyte) must be added to 49.3 mL of benzene (the solvent) such that the solution formed has a boiling point of 81.4 degrees celsius?
