Q. According to legend, to determine whether the king's crown was made of pure gold, Archimedes measured the crown's volume by determining how much water it displaced. The density of gold is 19.3 g/cm3. If the crown's mass was 6.00 ´ 102 g, what volume of water would have been displaced if the crown was indeed made of pure gold?
