Textbook Question

Chapter 7, Problem 7.70E

A technician dissolves 12.00 g of a nonvolatile solid into 100.0 g of methyl ethyl ketone (MEK). The vapor pressure of pure MEK is 99.40 mmHg , while the vapor pressure of the solution is 97.23 mmHg . What is the molar mass of the solid?

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
