naturally occuring chlorine is composed of 35CL with atomic mass of 34.969 37CL with atomic mass of 36.966 the average atomic mass id 35.453
what are the percantages of each isotope in naturally occuring chlorine ?
Let the fraction of Cl-35 be x and that of Cl-37 y.
(x)(34.969)+(y)(36.966)=35.453
Since the total of x and y must equal one, substitute y=1-x.
Solve for x. Solve for y. Multiply each one by 100 to convert to percent.
To find the percentages of each isotope in naturally occurring chlorine, we can use the formula:
% abundance of isotope = (mass of isotope / average atomic mass) * 100
Let's calculate the percentages for each isotope:
For isotope 35Cl:
% abundance of 35Cl = (34.969 / 35.453) * 100 = 98.680%
For isotope 37Cl:
% abundance of 37Cl = (36.966 / 35.453) * 100 = 1.320%
Therefore, in naturally occurring chlorine:
- 35Cl isotope makes up approximately 98.680% of the chlorine.
- 37Cl isotope makes up approximately 1.320% of the chlorine.
