2. A solution was produced by dissolving 3.75 g of a nonvolatile solute in 95g of
acetone. The boiling point of pure acetone was observed to be 55.95 ºC, while the boiling
point of the solution was 56.50ºC. If the boiling point for acetone is 1.71ºC/m, what is the
approximate molar mass of solute?
Step 1: First compute the molality of the boiling point equation.
Step 2. Then, from the definition of molality, compute the number of moles
solute, n(solute), in the sample.
Step 3. Solve for the molar mass.

5. The tone of the poem changes from the first stanza to the last stanza. Identify and explain the tone in the first and last stanza and reflect on the change that occurs. Your answer should include one word to describe the tone in the first stanza, with a reason for an answer, and one word to describe the tone in the last stanza, with the reason for an answer. Explain how the tone has changed.
6. Identify and explain the main theme of the poem. Refer to the title of the poem to explain your answer.

1. A solution containing 4.50 g of a non electrolyte (i=1) dissolved in 125 g of water
freezes at -0.372ºC. Calculate the molar mass of the solute.
Step 1: First compute the molality of the freezing point equation.
Step 2. Then, from the definition of molality, compute the number of moles
solute, n(solute), in the sample.
Step 3. Solve for the molar mass.
