Ch 13 Problems 1. What is the mass percent of a solution when 15.4 g of sodium phosphate is dissolved in 56.5 g of water? 2. How many milliliters of a 15.5% mass percent potassium carbonate solution to obtain 3.65 g of potassium carbonate? (Assume the density of the solution is 1.00 g/ml) 3. What is the mass percent of a 0.15 M sucrose (C 12 H 22 O 11 ) solution? (Assume that the density of the solution is 1.00 g/ml) 4. 25.3 ml of a 3.5% mass percent sodium hydroxide solution is neutralized by 18.7 ml of an acetic acid solution. What is the mass percent concentration of the acetic acid solution? (Assume that the density of solution for both the sodium hydroxide solution and the acetic acid solution is 1.00 g/ml) 5. 52.4 g of an iron (II) chloride sample is dissolved in water up to a volume of 450 ml. What is the concentration of the solution in molarity? 6. 112 g of a barium sulfide sample is dissolved in water. What is the final volume in liters of the solution if the final concentration is 3.57 M?
