* A 72112:08 stc “.ull a a Archimedes supposedly was asked to determine whether a crown made for the king consisted of pure gold. According to legend, he solved this problem by weighing the crown first in the air and then in water as shown in Figure. Suppose the scale read 6.57 N when the crown was in the air and 5.92 N when it was in the water. What is the density of the crown (in g/em) ? (gold density is 19.3 g/cm) (Answer in 2 decimal places)
