Some of the cyclohexane solvent vaporized during the temperature versus time measurement. Will this loss of cyclohexane result in its freezing point being recorded as too high, too low or unaffected? Explain.

Please someone explain this to me I don't understand it...Thank you

Are you measuring the f.p. of the cyclohexane solvent or the freezing point of the solute? If the solute, what is the solute? Are you using the depression of freezing point method?

• CHM -

freezing point of cyclohexane...yes I am using the depression of freezing point method

• CHM -

If there is no solute in the cyclohexane then the amount will not affect the f.p. In other words, the f.p. of cyclohexane is the same whether you've tested 1 mL or 100 mL
