The average molar mass of chlorine is

35.5\,g\,\,\,mo{l^{ - 1}}.

The ratio of

{}^{35}Cl

{}^{37}Cl

in naturally occurring chlorine is close to

View answer and explanation

Correct option: B

0.125694444

Option A (0.167361111) is incorrect. The correct answer is derived from setting up a weighted average equation and solving for the ratio of the isotopes.
