NaOH + HCl -> NaCl + H2O

What is the molarity of a NaOH solution that required 31.6mL to neutralize 25.0mL of a 0.145 M HCl solution?

• chemisty -

mols HCl = M x L = ?
mols NaOH = mols HCl(look at the coefficients in the balanced equation.
M NaOH = mols NaOH/L NaOH. You know L and you know mols, solve for M NaOH.
