How much 0.300 M NaOH is required to completely neutralize 30.0 ml of 0.15 M HClO4
I still don't get it to i times .300x30.0 then times .300 x.15 i just don't understand what i am actually suppose to multiply
M NaOH x mL NaOH = M HClO4 x mL HClO4
0.300M x mL NaOH = 0.15M x 30.0 mL
You have one unknown; i.e., mL NaOH. Solve for that.
