4. A sample of a zinc alloy is found to be 95.7% zinc by mass. The alloy has a density of 8.72 g/cm. How many ounces of zinc are present in a 2.4 in sample of the alloy? 5. How many mL of a salt water solution (35.0% salt by mass) is needed to obtain 57.6 grams of salt upon evaporation of the water? The density of the solution is 1.045 g/mL. 6.
