What is the density and molar mass for stearic acid?
You determined the molar mass of an unknown fatty acid 3 dissolved into stearic acid to be 219.4 g/mol. Unknown fatty acid 3 was myristic acid, which has a molar mass of 228.37 g/mol. What was your percent error to the correct number of significant figures?
1.0345 g of palmitic acid dissolved in 8.7545 g of stearic acid. Calculate the freezing point of the solution. The molar mass of palmitic acid is 256.48 g/ mol. The molal freezing point constant , Kf for stearic acid is 4.5 degrees C/ m and pure stearic acid freezes at 69.3 degrees Celsius.
