A scientist wants to check the fuel used in a failed experiment by doing a saponification analysis. He added equal amounts of excess KOH to a blank solution and a solution containing 1.25 g of the fuel. He titrated it with 0.5 M HCl titrant. The results are the following: ml HCl sample blank Vi .8 2.4 Vf 24.8 42 Show the solutions: 1. Saponification number (SN) of the oil sample? 2. The main component of the oil sample is a diglyceride, calculate the MW of the sample.

Question
A scientist wants to check the fuel used in a failed experiment by doing a saponification analysis. He added equal amounts of excess KOH to a blank solution and a solution containing 1.25 g of the fuel. He titrated it with 0.5 M HCl titrant. The results are the following:
| ml HCl | sample | blank |
| Vi | .8 | 2.4 |
| Vf | 24.8 | 42 |
Show the solutions:
1. Saponification number (SN) of the oil sample?
2. The main component of the oil sample is a diglyceride, calculate the MW of the sample.
