It takes 62 mL of 0.124 M KOH to neutralize
46.7 mL of H2SO4 solution. What is the
concentration of the H2SO4 solution?
Answer in units of moles/liter
2KOH + H2SO4 = K2SO4 + 2H2O
mols KOH = M x L = ?
mols H2SO4 = 1/2 that--Look at the coefficients in the balanced equation.
M H2SO4 = mols H2SO4/L H2SO4. You know L H2SO4 and mols, solve for M.
