Base your answer to the question on the information below. in a titration, a few drops of an indicator are added to a flask containing 35.0 milliliters of hno3(aq) of unknown concentration. after 30.0 milliliters of 0.15 m naoh(aq) solution is slowly added to the flask, the indicator changes color, showing the acid is neutralized. which choice is a correct numerical setup for calculating the concentration of the hno3(aq) solution? ma(35.0 ml) = (0.15 m)(30.0 ml)ma (0.15m) = (35 ml)(30ml)ma (30m) = (0.15m)(30.0ml)ma (35ml) = (0.15ml)(30.0m)
