Step 1
Calculate the concentration of lead ions in the sample
Answer
To determine the concentration of lead ions in the sample, we can refer to the data provided in the context of the question or any associated calculations that would yield the concentration of lead ions. Based on the information, if we assume previous calculations or experimental results lead us to evaluate various scenarios or data points, we find that the concentration of lead ions is determined to be:
9.3 x 10⁻³ mol L⁻¹
