Q1 & Q2
Q1. Part A.3. 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. (3 pts.) Q2. Part A.3. The digital thermometer is miscalibrated by +0.15°C over its entire range. If the same thermometer is used in part B.2, will the reported moles of solute in the solution be too high, too low, unaffected. Explain. (2...

Molecular Mass by Freezing point Depression (Preliminary Lab) The following errors occurred when the above experiment was carried out
Molecular Mass by Freezing point Depression (Preliminary Lab) The following errors occurred when the above experiment was carried out. How would each affect the calculated molecular mass of the solute (too high,too low, no effect)? Explain your answer. (a) The thermometer uses actually read 1.4C too high. (b) Some of the solvent was spilled before the solute was added.

Post Lab Questions 1. in a hurry to complete the experiment, the student failed to calibrate the Spectrophotometer. As a result, all absorbance values for the standard solutions that are measured and recorded are too high. How will this affect the following calculations in Part B? a. Will the calculated equilibrium concentrations of FeSCN** be too high, too low, or unaffected? Explain. b. Will the calculated equilibrium constants be too high, too low, or unaffected? Explain. 2. In Part A,...

Lab 3: Determination of Molar Mass by Freezing Point Depression 1 During winter, several different "salts" are used to melt ice sodium chloride (NaCI), a mix of sodium chloride and magnesium chloride (NaCl and MgCla calcium magnesium acetate (CaMg(CHO)). Assume you have 1 mole of each of these in 1 kg of water. Compare the freezing point depressions of these three "salts." a. b. What is the ratio of moles of "salt" to freezing point depression for each? What is...
