How big is a million dollars? At the time this text was written, the price of gold was about $1400 per ounce, while that of silver was about $20 an ounce. The “ounce” in this case is the troy ounce , which is equal to 31.1035 g. (The more familiar avoirdupois ounce is equal to 28.35 g.) The density of gold is 19.3 g/cm 3 and that of silver is 10.5 g/cm 3 . (a) If you found a spherical gold nugget worth $1 million, what would be its diameter ? (b) How much would a silver nugget of that size be worth?
