A chemistry teacher needs to mix an acid solution for an experiment. how much hydrochloric acid needs to be mixed with 1500 milliliters of water to make a solution that is 12% acid
1500 x 12% = 180mL To get this answer, you have to multiply the 1500mL by 12% (0.12) and get 180. This means that 12% of your 1500mL solution will be 180mL of hydrochloric acid.
