We calculate the number of moles of NaOH added: \[(5.1079\; mol/L)(46.67\; mL)= 238.4\; mmol\] This is also the number of moles of HCl in the original 100.00 mL of solution, because the reaction ratio is 1:1. To calculate the concentration of the HCl solution, we just divide the number of moles of HCl by the volume.
