Answer :
Final answer:
In a given sample of chlorine, the percentage of the heavier isotope (³7Cl) is 24.24%. This is inferred by representing the fractional presence of the isotopes in an equation and solving for each.
Explanation:
The atomic weight of Chlorine is 35.5, and it exists primarily in two isotopes, ³5Cl and ³7Cl, with atomic weights of 35 and 37 respectively. If x represents the fraction of ³5Cl, then the fraction of ³7Cl is represented by 1 - x. The solution to this equation is x= 0.7576 which implies that Chlorine consists of 75.76% ³5Cl and 24.24% ³7Cl. This showcases that in a given sample of Chlorine, 24.24% would be the heavier isotope, ³7Cl.
