Silver has two naturally occurring isotopes, 107Ag (isotopic mass 106.90509 amu) and 109Ag (isotopic mass 108.90476 amu). If silver has an atomic mass of 107.87 amu, what is the percent abundance of 109Ag isotope? (Attention: Show the equation with the variable x to gain the credit by using the Function button of "Insert Math Equation" in the panel above. All you need to type in the box below are the equation and the result. Calculation result without the equation will only give you no more than 30% of the credit.)
Chromium which has an average atomic mass of 51.9961 amu has four isotopes. The masses of its isotopes are 49.94605 amu, 51.94051 amu, 52.94065 amu and 53.93888 amu.

Boron (B; Z=5) has two naturally occurring isotopes. Find the percent abundances of 10B and 11B given the atomic mass of B=10.81 amu, the isotopic mass of 10B = 10.0129 amu, and the isotopic mass of 11B = 11.0093 amu. (Hint: the sum of the fractional abundances is 1. If x = abundance of 10B, then 1-x=abundance of 11B) Atomic Wt = Isotopic Mass 10B(proportion) + Isotopic Mass 11B(proportion)
