(a) To identify a liquid substance, a student determined itsdensity. Using a graduated cylinder, she measured out a 45-mLsample of the substance. She then measured the mass of thesample, finding that it weighed 38.5 g. She knew that the substancehad to be either isopropyl alcohol (density 0.785 g/mL)or toluene (density 0.866 g/mL). What are the calculated densityand the probable identity of the substance? (b) An experimentrequires 45.0 g of ethylene glycol, a liquid whose densityis 1.114 g/mL. Rather than weigh the sample on a balance, achemist chooses to dispense the liquid using a graduated cylinder.What volume of the liquid should he use? (c) Is a graduatedcylinder such as that shown in Figure 1.21 likely to afford theaccuracy of measurement needed? (d) A cubic piece of metalmeasures 5.00 cm on each edge. If the metal is nickel, whosedensity is 8.90 g/cm3, what is the mass of the cube?

A supersaturated sugar solution (650.0 g sugar in 150.0 g water) is prepared to make rock candy. The solution is kept at 25C, where the solubility of sugar is 220.0 g/100 g water. A string is dipped into the solution, and in time, large crystals of sugar (rock candy) form. How many grams of solid are obtained when the solution just reaches saturation?
Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. Its solubility in water at 20C is 54.6 g/100 g. At 80C, its solubility is 66.1 g/100 g.

If it is, how many more grams of magnesium chloride are required to make a saturated solution? If the mixture is not homogeneous, how many grams of magnesium chloride are undissolved? (b) How many more grams of magnesium chloride are needed to make a saturated solution at 80C?
