In the scary chemical storage room, you spot a bottle of potassium hydroxide solution, KOH, without a label noting its concentration! How terrible! (the nerve of some people...) Since you love chemistry, you decide to figure out its concentration by doing a titration. You add 5.00mL of 0.100M phosphoric acid to a flask and add KOH solution until it's all neutralized! If 5.00mL of potassium hydroxide solution were used in the titration, what is its concentration? 3.00 M 0.900 M 5.00 M 0.100 M 0.300 M
