## Chemistry and Chemical Reactivity (9th Edition)

Since all these solutions are of non-volatile nonionic solutes in the same mass of water, the one with the highest boiling point will be the one with the higher number of moles: sucrose: $3.0\ g/342.30\ g/mol=0.009\ mol$ glycerol: $1.0\ g/92.09\ g/mol=0.011\ mol$ propylene glycol: $1.0\ g/76.10\ g/mol=0.013\ mol$
