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

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
