Pb has an average atomic mass of 207.19 amu. The three major isotopes of Pb are Pb-206 (205.98 amu); Pb-207 (206.98 amu); and Pb-208 (207.98 amu). If the isotopes of Pb-207 and Pb-208 are present in equal amounts, calculate the percent abundance of Pb-206, Pb-207, Pb-208. Percent abundance of Pb-206 is % (3 sig fig) Percent abundance of Pb-207 is % (3 sig fig) Percent abundance of Pb-208 is % (3 sig fig)
