Question

What must be the molarity of an aqueous solution of NH3 if it is 4.3 % ionized? Express your answer using two significant figures.

For the answer, I got the following, but it says I rounded wrong. I redid this problem so many times. IDK where i went wrong.

ANSWER 1: (NH3]initial = 0.0096 M Check your rounding. Your final answer should be rounded to 2 significant figures in the la
