The experiment involves diluting a 16% sugar solution, prepared by dissolving 16 g of sugar in 100 mL water. Three different solutions are prepared by mixing the 16% sugar solution with various volumes of water.Make appropriate choices from the dropdowns. Work from left to right. Each answer can be calculated from numbers to the left of it in the row.

A student is given a sample of a pink manganese (II) chloride hydrate. She weighs the sample in a dry, covered crucible and obtains a mass of 26.742g for the crucible, cover, and sample. Earlier she had found that the crucible and cover weighed 23.599g. She then heats the crucible to drive off the water of hydration, keeping the crucible at red heat for about 10 minutes with the cover slightly ajar. She then lets the crucible cool and finds it has a lower mass; the crucible, cover and contents then weigh 25.598g. In the process the sample was converted to off-white anhydrous MnCl2. a. What was the mass of the hydrate sample? _ghydrate b. What is the mass of the anhydrous MnCl2? _gMnCl2 c. How much water was driven off? _gH2O d.
