My problem is calculate the molarity of HCl and NaOH.

(molarity of acid)x(volume of acid)=(molarity of base)+(volume of added base)

HCl=acid NaOH=base

HCl volume = 25mL=0.025L
NaOH=67.05mL=0.06705

molarity = moles of solute
Liters of a solution
M=0.015000 moles of NaOH
0.06705L
M1V1=M2V2
M1V1=M2V2
V1
M1=M2V2
V1
M1=0.223713647 M of NaOH * 0.06705L
0.025L
M1=0.600000001M of HCl

0.600000001 M of HCl* 0.025L =
0.223713647 M of NaOH * 0.06705L

Am I even close?

1. You would have done much better to type in the problem before showing your solution. It's good to show your work, however, you have no data (at least none identifiable). For example, where did the 0.01500 mols come from? Finally, you have made a typo in the second sentence (the formula). You show a + sign and it should be a x sign. If you will post the problem someone will go through and check it for you. Thanks for using Jiskha.

2. Calculate the molarity of the HCl from the volumes of acid and base and the molarity of the NaOH. Use the following equation:

(molarity of acid)x(volume of acid)=(molarity of base)x(volume of added base)

equivalance point=number of mL of base to an acid

1mL=0.001L

HCl volume=25 mL=0.025L
NaOH=67.05mL=0.06705L

Molarity=Moles of solute
