Chemistry

A 2.250Ã—10^âˆ’2 M solution of glycerol (C3H8O3) in wateris at 20.0âˆ˜C. The sample was created by dissolving a sample ofC3H8O3 in water and then bringing the volume up to 1.000 L. It wasdetermined that the volume of water needed to do this was 999.0 mL. The density of water at 20.0âˆ˜C is 0.9982 g/mL.
Part A:Â Â
Calculate the molality of the glycerol solution.
Express your answer to four significant figures and include theappropriate units. Definitely not 0.0225
Part B: Calculate the mole fraction of glycerol in thissolution.
Express the mole fraction to four significant figures.definitely not 55.40
Part C:Â Â Calculate the concentration of the glycerolsolution in percent by mass.
Express your answer to four significant figures and include theappropriate units. definitely not 0.002
