State what is the age of a mineral mass ratio

Reference no: EM13176753

The ratio of 238U to 206Pb is used to date old mineral samples. Each 1.000 g of 238U that decays eventually produces 0.866 g of 206Pb. If the half-life of 238U is 4.468 x 10^9 years, what is the age of a mineral that has a 238U/206Pb mass ratio of 2.00?

The correct answer is 2.94 x 10^9 years
