Calculate the amount of: a) Glucose, in grams, that must be dissolved in water to obtain 75 ml of a 0.350 M solution of C6H12O6. b) Methanol, CH3OH (ρ=0.792 g/ml), in ml, which must be dissolved in water to obtain 2.25 L of a 0.485 M CH3OH solution

Calculate the molarity of HCl in a solution, which was prepared by dissolving 5.5 g of HCl (molar mass = 36.46 g/mol) in 200 g of C2H60. The density of the solution is 0.79 g/mL.

An aqueous Na;PO, solution is made using 42.3 g of Na:PO, diluted to a total solution volume of 2.00 L. 163.94 g NazPO4) (molar mass 1 mole Na3P04 a) In one calculation string, show the calculation for determining the molarity of the sodium phosphate solution. b) In one calculation string, show the calculation for determining the mass percent of the sodium phosphate solution from the molarity you determined in part a. c) Show the necessary calculations for determining the molality of sodium phosphate solution from the molarity you determined in part a. These calculations should be as condensed as possible, but don't need to be in one string. Assume a density of 1.08 g/mL for the solution.
