Chapter 1, Problem 1.60E

9.1. The egg whites from four "large" eggs occupy a volume of 112mL. The mass of the egg whites from these four eggs is 1.20 X 102 g. What is the average density of an egg white from one "large" egg?   9.2. A solid with an irregular shape and a mass of 11.33 g is added to a graduated cylinder filled with water (d=1.00g/mL) to the 35.0-mL mark. After the solid sinks to the bottom, the water level is read to be at the 42.3-mL mark. What is the density of the solid?   9.3. Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. Its solubility in water at 20oC is 54.6 g/100 g. At 80oC, its solubility is 66.1 g/ 100 g. A mixture is made up of 16.2 g of magnesium chloride and 38.2 g of water at 20oC. a. Is the mixture homogeneous? 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…

How many significant digits should be reported in the answer to the following calculation?(4.213) + (10.02) =  a. 3 b. 4 c. 2 d. 1 e. none of the above.

b. (6.0241 X 1.24) / (.0147 X 10.0) = * c. The density of an object that has a mass of 16.0 grams and a volume of 35 mL? d. The volume of 65.4 grams of silver if the density of silver is 10.5 g/mL? e. An object is placed in a graduated cylinder containing 20.5 mL of water. The water level rose to 28.5 mL. If the object has a mass of 42.3 grams, what is the density of the object? S f. A student measures the volume and mass of a piece of sodium chloride and calculates the density of sodium chloride to be 2.245 g/cm³. He then looks in his textbook and finds that the actual density of sodium chloride is 2.156 g/cm³. What is his percent error?
