Polonium-210, 210Po, decays to lead-206, 206Pb, by alpha emission according to the equation 84Po210 → 82Pb206 + 2He4 If the half-life, t1/2, of 210Po is 138.4 days, calculate the mass of 206Pb produced from a 574.0 mg sample of Polonium(IV) chloride, PoCl4, that is left untouched for 333.5 days. Assume that the only polonium isotope present in the sample is the 210Po isotope. The isotope molar masses of 210Po is 209.98 g/mol and 206Pb is 205.97 g/mol.
