13. A certain element has two stable isotopes. The mass of one of the isotopes is 62.93 amu and the mass of the

other isotope is 64.93 amu. Determine the percent abundance of each isotope.

14. Indium (In) has two isotopes, Indium-113(amu= 112.904) & Indium-115 (amu=114.904). The average atomic

weight of indium is 114.818 amu. Determine the percent abundance of each isotope. Answer should be given to the

hundredths place.

15. Chlorine (Cl) has two isotopes, chlorine-35(amu= 34.969) & chlorine-37(amu=36.966). The average atomic

weight of chlorine is 35.4527 amu. Determine the percent abundance of each isotope. Answer should be given to

the hundredths place.

16. Element X is found in two forms: 90% is an isotope that has a mass of 20.0 and 10% is an isotope that has a

mass of 22.0. What is the atomic mass of element X?

17. What is the average atomic mass of a hypothetical sample of element X if it is found that 20% of the sample

contains an isotope with mass of 100; 50% of the sample contains an isotope of the element with mass of 102; and

30% of the sample contains an isotope of the element with a mass of 105?
