Archimedes' principle can be used to calculate the density of a fluid as well as that of a solid. Suppose a chunk of copper with a mass of 475.0 g in air is found to have an apparent mass of 438.3 g when completely submerged in an unknown liquid. (a) What mass (in g) of fluid does the copper displace?  g (b) What is the volume of copper (in cm3), using its density as given in this table?  cm3
