Part C A sucrose solution is prepared to a final concentration of 0.140 M. Convert this value into terms of g/L, molality, and mass %. (Use the following values: molecular weight MW sucrose = 342.296 g/mol; density Psol'n = 1.02 g/mL ; and mass of water, mwat=972.1 g). Note that the mass of solute is included in the density of the solution. Express the concentrations in grams per liter, molality, and mass percent to three significant figures separated by commas. ► View Available Hint(s) | Doto r o for Part redo for eart C restor Part C keyboard shortcuts for Part C help for Part C sucrose concentrations = 47.9,1.4410-4,4.93 Submit Previous Answers X Incorrect; Try Again; 2 attempts remaining for Part for Part Gravimetric analysis Gravimetric analysis is a technique by which information is obtained based on massed values. One application of gravimetric analysis can allow the solubility of a solid to be determined. This is achieved by adding a known mass of solid to solution, then…

A scientist needs to make a 250 mL of a solution of ethanol in water that has a molaritv of 0.12 Unfortunately, the only scales are available. [Water: M = 18.02 g/mol, d=0.997 g/mL] [Ethanol: M = 46.07 g/mol, d = 0.789 g/mL]) a. Calculate the mass of each substance needed to make this solution. b. Calculated the volume percent of each substance?
