Polonium-210, 210Po, decays to lead-206, 206Pb, by alpha emission according to the equation

210Po84 right arrow 206Pb82 + 4He2

If the half-life, t1/2, of 210Po is 138.4 days, calculate the mass of 206Pb that can be produced from a 575.0-mg sample of polonium(IV) chloride, PoCl4, that is left untouched for 331.4 days. Assume that the only polonium isotope present in the sample is the 210Po isotope. The isotopic molar masses of 210Po is 209.98 g/mol and 206Pb is 205.97 g/mol.
