5.A. Syrup, USP is prepared by dissolving 850 g of sucrose in sufficient purified water to make 1000 mL of syrup. Syrup has a specific gravity of 1.31. How many milliliters of water are used to prepare a liter of syrup? 5.B. A saturated solution of potassium iodide contains, in each 100 mL, 100 g of potas- sium iodide. The solubility of potassium iodide is 1 g in 0.7 mL of water. Calculate the specific gravity of the saturated solution.

Chemistry A 76.0 mL portion of a 1.30 M solution is diluted to a total volume of 238 mL. A 119 mL portion of that solution is diluted by adding 177 mL of water. What is the final concentration? Assume the volumes are additive.

13. A chemistry student offers a possible improvement to this lab. Since one goal of this lab is to determine the mass of the precipitate produced, wouldn't it be possible to measure the mass of an empty beaker, mix the solutions, and boil off the water until it is entirely evaporated, leaving only solid behind? Then the beaker with the precipitate could be weighed, and the difference between this mass and that of the empty beaker would be the mass of the precipitate. This would eliminate the need for the filtration step. Explain why this is a poor suggestion. Remember to check your reasoning on this question and all other questions with your instructor.
