Question

Two students prepare two cyclohexane solutions having the same freezing point. Student 1 uses 26.6 g of cyclohexane solvent, and student 2 uses 24.1 g of cyclohexane solvent. Which student has the greater number of moles of solute? I tried the problem using the following equation ( I do not know if it is the right equation to be using however): moles solute = Delta Tf (change in freezing point) x mass (kg) of solvent / kf kf of cyclohexane= 20.0 I'm not sure what to do next since no change in freezing point was given. Any help would be much appreciated :) Note: I'm reposting this question because some of the explanations I have found so far did not make sense.

Explanation / Answer

Do you go to NOVA, and do you have a lab at the annandale campus?
