At one point in time, 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 $5.00 million, what would be its diameter? b)How much would a silver nugget of that size be worth?
