(_) measured was higher (o) measured was lower (_) they were the same (_) cannot predict from the information given Question 3b In Part B for the first solution made by adding lauric acid, calculate the % difference. The equation for percent difference is: % difference = ((theoretical value - actual value) x 100%) / theoretical value. A percent difference can be positive or negative.% Difference = 1.07Question 4 In Part B for the second solution made by adding lauric acid, did you expect the freezing point to be at a higher or lower temperature thatn that of the pure solvent, stearic acid?(_) higher (o) lower (_) the same (_) cannot predict from the information given Question 6a In Part B for the second solution made by adding lauric acid, how did your measured freezing point compare to your theoretical freezingpoint? (_) measured was higher (o) measured was lower (_) they were the same (_) cannot predict from the information given Question 6b In Part B for the second solution made by adding lauric acid,calculate the % difference. The equation for percent difference is: % difference = ((theoretical value - actual value) x 100%) / theoretical value.A percent difference can be positive or negative.% Difference = 1.422. 15/15 points Last Response | Show Details All Responses Notes Type your name in the answer box.
