The mixture is 40% Chlorine-37 and 60% Chlorine-35. Predict the approximate atomic mass of this mixture.

A. 36.6 amu
B. 36.8 amu
C. 37.2 amu
D. 37.6 amu

Answer :

Final answer:

Using the given percentages for Chlorine-35 and Chlorine-37, and the weighted average formula for atomic mass, the atomic mass calculated for the given mixture is 35.8 amu, which does not match any of the provided answer choices.

Explanation:

The problem involves the calculation of the average atomic mass of chlorine based on the given percentages of its two isotopes. The mentioned isotopes are Chlorine-35 (35Cl) and Chlorine-37 (37Cl), contributing 60% and 40% to the mixture respectively.

To calculate the atomic mass of this mixture, we use the formula for weighted averages:
Atomic Mass = (% of 1st isotope * 1st isotope's atomic mass) + (% of 2nd isotope * 2nd isotope's atomic mass)
Plugging in the given values: Atomic Mass = (0.60*35) + (0.40*37) = 21 + 14.8 = 35.8 amu.
Therefore, among the given options, none match the calculated atomic mass. There might be a typographical error in the options provided in the question.
