Molecular Mass by Freezing Point Depression Essay

Analysis1.)Determine ___ for the solution of cetyl alcohol and of the unmapped significance in BHT. 2.)Calculate the molality of the cetyl alcohol solution and use it to target the value of the freezing point depression constant,____, for BHT. 3.)Use the calculated value of ___ to uprise the molecular mass of the inglorious solute.Discussion1.Give a definition of colligative properties.2.Draw a phase diagram of a clear substance, and show how addition of a solute affects this diagram. 3.What is the least precise measurement? How does this limit your significant digits? 4.Why is it advantageous to postulate a solvent that has a large value for ____? 5.Explain why the pure solvent shows a level horizontal curve as solidification occurs, but the curve for the solution slopes downward slightly.ConclusionI answered the quarry because I was able to determine the molecular mass of the unknown substance by finding the change in freezing point of BHT when the unknown substance was di ssolved in it. I learned how to apply __fp and molality. both errors that couldve occurred were timing the freezing pointcorrectly and we might not contribute had one cen termter in the capillary tubing tube. We didnt know that we were supposed(a) to stop timing after it started to become transparent, so our timings were all from when the complete centimeter of solution was transparent (except for trial 2).This would experience affected our results by making our melting point temperature higher than it really should be. Since we didnt collect exactly one centimeter, the reader could have not seen when it first started. Thus, our time wouldve been higher than it should be too. Two improvements would be making sure we have exactly one centimeter or more in our capillary tubes and possibly just timing our results for a more
