Suppose you are asked to determine whether a nugget is made of gold on the basis of its density. You weigh the nugget and find that it has a mass of 163 grams (g). Then you carefully add it to a graduated cylinder that contains 50.0 milliliters (mL) of water and observe that the water level in the cylinder rises to 58.5 mL. What is the density of the nugget in grams per cubic centimeter?
