A 2.100×10−2 M solution of glycerol (C3H8O3) in water is at20.0∘C. The sample was created by dissolving a sample of C3H8O3 inwater and then bringing the volume up to 1.000 L. It was determinedthat the volume of water needed to do this was 999.1 mL . Thedensity of water at 20.0∘C is 0.9982 g/mL.
a.) Calculate the molality of the glycerol solution. Expressyour answer to four significant figures and include the appropriateunits.
