A student follows a lab protocol that asks them to make an ‘alcohol’ solution for an experiment. They make a 1.00 L solution by adding 575 g of an alcohol to water. Later they realize that there were three different alcohols sitting on the lab bench and they’re not sure which one they used. The alcohols are: methanol (CH3OH), ethanol (C2H5OH), and butanol (C4H9OH). They decide to boil the solution and they find that it boils at 106.40 °C. Using this information determine which alcohol the student used to make their solution. Density of water is 1.00 g/mL, Kb = 0.513 K/mc. Hint: you need to consider the molar masses of your alcohols.
