Question 1

A solution of CH₃OH in H₂O would most likely:

◦ be ideal.
◦ show positive deviations from Raoult's law.
◦ show negative deviations from Raoult's law.
◦ not be ideal, but the deviations cannot be predicted.
◦ obey Raoult's law.

Question 2

A solution of hydrogen peroxide is 23.1% H₂O₂ by mass and has a density of 1.11 g/cm³. The molarity of the solution is:

◦ 7.08 M
◦ 0.256 M
◦ 7.54 M
◦ 7.86 M
◦ none of these are correct
