To measure the density of a small statue, you determine the mass of the statue to be 2.219 kg. Next, you pour 400 milliliters of water into a graduated cylinder (measured to the nearest mL). You then gently lower the statue into the water and observe that the volume rises to 682 milliliters. Calculate the density of the statue. Based on Table 2.8, what element might the statue be made of? 96.
