calculate the number of atoms in 100.0g of mercury:
Part 3: Average Mass:
Atomic Mass = (0.1687 X 198.968254) + (0.2310 X 199.968300) +
(0.1318 X 200.970277) + (0.2986 X 201.970617) = 166.35 amu
Isotope: 199Hg, 198.968254 amu, 16.87 % abundance
Isotope: 200Hg, 199.968300 amu, 23.10 % abundance
Isotope: 201Hg, 200.970277 amu, 13.18 % abundance
Isotope: 202Hg, 201.970617 amu, 29.86 % abundance
Part 4: Use the average mass calculated in Part 3 to calculate
the number of atoms in 100.0g...
