Question

Please help? I don't know how to solve for concentration:
If it requires 25.0 milliliters of 1.0 molar HCl to neutralize 45.0 milliliters of NaOH, what is the concentration of the NaOH solution?

Balanced equation: NaOH + HCl yields NaCl + H2O

0.56 M NaOH

0.82 M NaOH

1.1 M NaOH

1.8 M NaOH

Answer 1

Would it be something like:

n = c x v = 1 x 0.025 = 0.025 moles = n
NaOH = n/v = 0.025/0.045 = 0.56M

So is it A? 0.56 M NaOH?

Answer 2

That's the way to do it

Answer 3

Did you use M1V1=M2V2?
