Chapter 15, Problem 77P

You’re a private investigator assisting a large food manufacturer in tracking down counterfeit salad dressing. The genuine dressing is by volume one part vinegar (density 1.0g/cm³) to three parts olive oil (density 0.92 g/cm³). The counterfeit dressing is diluted with water (density 1.0 g/cm³). You measure the density of a dressing sample and find it to be 0.97 g/cm³. Has the dressing been altered?

You are making banana bread and the recipe calls for 3/4 cup of vegetable oil and one egg yolk. You measure out your oil in a measuring cup and then just toss the egg yolk into the oil before mixing with the dry ingredients. The egg yolk has a mass of 9.9 grams and floats with 71 % of its volume under the surface of the oil. You also know that the density of the oil is Poil 0.95 cm³ What volume of oil is displaced by the egg yolk? cm3 What is the total volume of the egg yolk? cm³ What is the density of the egg yolk? g cm3 Imagine the egg yolk was floating in a salt-water solution instead (Pwater = 1.04 % .). What percentage of the yolk would be submerged in water? cm³
