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,

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
