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

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
