An environmental chemist obtained a 200 mL sample of lake waterbelieved to be contaminated with a single monoprotic strong acid.Titrating this sample with a 0.0050 M NaOH(aq) required7.3 mL of the NaOH solution to reach the endpoint. If the size ofthe lake can be approximated as 1.1 km long by 2.3 km wide, and hasan average depth of 10 m, estimate how many moles of the strongacid are present in the lake?
