Only two stable isotopes of chlorine exist. 35cl has a mass of 34.96885 amu and 37cl has a mass of 36.9659 amu. given that the atomic mass of chlorine is 35.453, calculate the isotopic abundance of 37cl. (enter your answer as a decimal number between zero and one.)

The isotopic abundance of Cl- 37 is 0.2424.

Explanation:

Mass of isotope - 35 = 34.96885 amu

% abundance of isotope -35= x% =

Mass of isotope - 37 = 36.9659 amu.

% abundance of isotope-37 = (100-x)% =

Formula used for average atomic mass of an element :

Therefore,  the isotopic abundance of Cl- 37 is 0.2424.
