Textbook Question
Chapter 1, Problem 1.74SP
You would like to determine if a set of antique silver ware is pure silver. The mass of a small fork was measured on a balance and found to be 80.56 g. The volume was found by dropping the fork into a graduated cylinder initially containing 10.0 mL of water. The volume after the fork was added was 15.90 mL. Calculate the density of the fork. If the density of pure silver at the same temperature is
