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. Chlorine has two naturally occurring isotopes, ${}^{35}Cl$ and ${}^{37}Cl$. If the atomic mass of Cl is $35.45$, the ratio of natural abundance of ${}^{35}Cl$ and ${}^{37}Cl$ is closest to:

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

Q. Chlorine has two naturally occurring isotopes,${}^{35}Cl$ and ${}^{37}Cl$. If the atomic mass of $Cl$ is 35.45, the ratio of natural abundance of ${}^{35}Cland{}^{37}Cl$ is closest to
