A uranium mineral contains \( \mathrm{U}^{238} \) and \( \mathrm{Pb}^{206} \) in the ratio \( 4: 1 \) by weight. Calculate the age of mineral
\( \mathrm{P} \)
\( \left(\mathrm{t}_{1 / 2}\right. \) for \( \left.\mathrm{U}^{238}=4.5 \times 10^{9}\right) \) years
(1) \( 1.66 \times 10^{9} \mathrm{yrs} \)
(2) \( 16.6 \times 10^{9} \mathrm{yrs} \)
(3) \( 16.6 \times 10^{10} \mathrm{yrs} \)
(4) None of these
