Chlorine is found as two isotopes, Cl-35 and Cl-37 (or and Cl). The atomic mass of the Cl-35-isotope is 34,96885 amu while the Cl-37-isotope has an atomic mass equal to 36,96590 amu ( The textbook use this unit for atomic mass, we could as well have used the recommended unit «u»). In the Periodic Table given in the textbook the molar mass of Chlorine is given as 35,45 g/mol. What is the percentage abundance of the two chlorine isotopes?
