60. If the average atomic mass of chlorine is 35.5, then find the percentage abundance of the two isotopes of chlorine which have the mass number 35 and 37

Q. Chlorine has two stable isotopes: Cl-35 and Cl-37 with atomic masses 34.96 and 36.95, respectively. If the average mass of chlorine is 35.43, calculate the percentage abundance.

Q. Chlorine has two naturally occuring isotopes ${}_{17}^{37}Cl$ and ${}_{17}^{35}Cl$ and average atomic mass of chlorine is $35.5$. The percentage of ${}_{17}^{37}Cl$ is:

Q. Atomic mass of chlorine is 35.5. It has two isotopes of atomic mass 35 and 37. The percentage of heavier isotope is:

Q. Chlorine has two common isotopes ${}^{35}Cl$ and${}^{37}Cl$, if the abundance of ${}^{35}Cl$ is $75.2$ and that of ${}^{37}Cl$ is $24.8$, what is the average atomic mass of chlorine?

Q. ${}_{17}^{35}Cl$ and ${}_{17}^{37}Cl$ are two isotopes of chlorine. If average atomic mass is $35.5$ then ratio of these two isotopes is:
