In a land far away, long, long ago, the king sent to the royal goldsmith a five pound ingot of pure gold. "From this gold", commanded the king, "fashion for me a crown". When the crown was presented to the king, he wondered whether the crown was truly pure gold or if the greedy goldsmith had cheated him by replacing part of the gold with copper. The king asked the court chemist to determine, without damaging the crown, whether it did indeed consist of pure gold. The chemist, being a clever soul (aren't they all), weighed the crown and found that it did, in fact, weigh precisely five pounds. The chemist then proceeded to immerse the crown in a flask of water. The flask, which initially contained 1000 mL of water, now appeared to contain 1170 mL of water. Knowing that the density of pure gold is 19.3 g/mL, what did the chemist tell the king?
