Question

5. Two Solutions are prepared using the same solution: Solution A: 0.27g of the solute dissolves in 27.4 g of t-butanol. Solution B: 0.23g of the solute dissolves in 26.8g of cyclohexane. Which solution has the greatest freezing point change? Show calculations and explain.

6. Experimental Procedure.

a. How many (total) data plots are to be completed for this experiment? account for each.

b. What information is to be extracted from each data plot?

I really need help with 6. I got the answers for 5, just provided it so you know which problem I'm stuck on.

Explanation / Answer

5

?Tf = Kf*m*i

since solute is same i will be the same for the two cases.

Now, for solving this problem u need Kf values for t-butanol and cyclohexane.

Kf t-butanol = -9.1
