A 1.05 gram sample of butter is refluxed with ethanolic KOH and required 10.4 mL of 0.1875 M HCl to reach the phenolphthalein end point. If blank determination required 27.7 mL of the same standard acid, calculate the saponification value. Calculate the saponification number. Assuming butter comprised mainly of fat, what is its molar mass?

Expert Solution

Assuming that butter comprises mainly of fat, the molar mass of the fat present should be equal to the amount of KOH it has neutralised = 173mg.
