3. An unknown element (X) is a mixture of three major isotopes shown in the table below. Mass (u) % Abundance Isotope 110x 111X 112X 109.994 110.958 111.973 32.000 ? The average atomic mass for X is determined to be 111.026 u (atomic mass units). What are the % abundances of isotopes X and ¹12X? (Hint: #87, # 88 of Ch. 3 Additional Problems)
