I really need help quickly! I will rate! Please include units.

Chemists often use molarity M, in moles/liter, to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure. However, the drawback of using molarity is that volume is a temperature-dependent quantity. As temperature changes, density changes, which affects volume. Volume markings for most laboratory glassware are calibrated for room temperature, about 20C. Fortunately, there are several other ways of expressing concentration that do not involve volume and are therefore temperature independent. and then bringing the volume up to 1.000L. It was determined that the volume of water needed to do this was 999.0mL. The density of water at 20.0C is 0.9982g/mL. Part A Calculate the molality of the glycerol solution.
