You use 30.50 mL of 0.1102 M HNO3(aq) to titrate 50.25 mL of NaOH(aq). a. Where is the NaOH(aq) located in the image below? The NaOH(aq) is located [ansA] because it is the [ansB] b. Where is the HNO3(aq) located? The HNO3(aq) is located [ansC] because it is the [ansD] c. What is the concentration of the NaOH(aq) solution? (3 sig. figs.). The NaOH(aq) has a concentration of [ansE] M.

You take 0.050 L of a 0.500 M solution of NH3 and you dilute it until the final volume of the solution is 0.250 L. What is the new concentration? Remember, M1 V1 = M2 V2 where M1 is the initial concentration, M2 is the final concentration and V1 and V2 are the initial and final volumes respectively.
