Post Lab Questions:

1. Trimyristin is a saturated fat because saturated fat contains no carbon at all. Monounsaturated contain only one carbon double bond as polyunsaturated fats contain two or more.
2. In a crystallization process, if it is cooled too fast then smaller crystals are formed compared to slow cooling that has bigger crystals. Quick cooling causes impure and defiled crystals as compared to slow cooling that has more pure crystals.
3. To calculate stearic acid upon hydrolysis of 1.8 g of tristearin, take the moles of tristearin. 1.8 / 891.48 = 0.002 moles. Then multiply by 3 to get 0.006 moles. Then multiply by the molecular mass of staeric acid which is 284.5 g/mol to get 1.7 g of stearic acid.
4. Heating up a mixture for a long period can boil the mixture speeding up the reaction time. Also, the mixture will mix well as it boils.
5. Heating something at not so high temperature for 45 minutes will just separate the compounds in the mixture itself.
