JJ Thomson. We were taught to remember JJ Watt, the football player because the first name is the same, and Watt is a type of electricity

0.72 mL of solution will have 180 mg of amoxicillin. For this problem, you need to calculate the equivalent ratio of volume as to the ratio of amoxicillin. So 180/500 = X/2.0 Multiply both sides by 2 2 * 180/500 = X 360/500 = X 18/25 = X 0.72 = X So you need 0.72 mL of solution to get 180 mg of the drug.
