I’m having trouble figuring out how to use the first page in answering the question CHM 232/EXPERIMENT F Lab Section 6) Date performed Record the following information during the laboratory period. Bucket number: Name lolia Laha Lab Partner Part 1: Saponification _1. Concentration ofHCl titrant 0.950 n Record the titration data for the saponification reaction below. Shaded boxes require no data. Show the units for each value given. Blank oil Butter Sample mass Final buret reading Initial buret reading Volume of HCl added 5. 60 15 60 8 80 Part 2: Trans fat content _1. A standard curve (Peak area versus % trans fat) from the standards (elaidic acid and soy oil) is displayed on the board. Write the equation of the regression line below. [1 pt :6.917x 6.74q 2. Report the value for the peak area that you obtained from the FTIR and calculate the % trans-fat content in the butter and in the margarine you analyzed in lab. Show your calculation below.

number of moles of OH- = number of moles of H+= concentration × volume
so, 1 mole of HCL reacts with one mole of OH- so number of moles of HCL =number of moles of OH-
number of moles of H+= concentration × volume
so for Blank, number of moles of HCL = 0.250 * 15.60 = 3.9 moles =number of moles of OH- in blank
and for soy oil, number of moles of HCL = 0.250 * 9.20 = 2.3 moles =number of moles of OH-
for butter, 0.250 * 8.80= 2.2 moles of OH-
