Geologists use the decay of potassium-40 in volcanic rocks to determine their age. Potassium-40 has a half-life of 1.26 x 10⁹ years, so it can be used to date very old rocks. If a sample of rock 3.78 x 10⁹ years old contains 2.73 x 10⁻⁷ g of potassium-40 today, how much potassium-40 was originally present in the rock? *
