If relative atomic mass (A_r) of Cl is 35.45, what is the ratio of ³⁵Cl:³⁷Cl present in a sample of Cl atoms containing naturally occuring Cl? (The answer is 3.17:1 but I don't know how the answer was obtained. Please workout out the solution and post it ASAP)

Naturally occurring cobalt consists of only one isotope,⁵⁹Co, whose relative atomic mass is 58.9332
amu. A synthetic radioactive isotope of cobalt, ⁶⁰Co,has a relative atomic mass of 59.9338 amu and is
used in radiation therapy for cancer treatment. A 1.5886 g sampleof cobalt has an apparent
