Scoring Scheme: 3-3-2-1 Part Il. The molality of a solution is the number of moles of the solute that is dissolved in 1000 g of solvent. Using the values for the mass of sodium chloride, its molar mass (58.443 g/mol), and the mass of water solvent that you used, calculate and enter the molality of the sodium chloride solution to three significant digits, e. g. 0.484 Submit Answer/Continue Quit Post-Lab 8) Data Entry-No Scoring Part I. Please enter the volume in mL of water to the nearest hundredth of a mL, e. g. 9.99 mL, that you used to prepare the sodium chloride solution, the freezing point of which you subsequently measured. Volume (ml) Your 10 No Points Possible 9) Scoring Scheme: 2-1 The density of water may be taken to be 0.9980 g/mL at 21°C. Considering the volume of water that you used to prepare the the sodium chloride solution, calculate the mass in grams of water. Enter the mass to the nearest thousandth of a gram. Your 9.98 You Scored 2 points out of 2 Possible 10) Data Entry No Scoring Part Il. Please enter the mass of sodium chloride that you used to prepare your solution in part Il of the experiment to a thousandth of a gram,
