One mole = molecular mass in grams (molar mass) = \ce 6.023 × 10 23 particles = 22.4 litres. mole = 10 / 36.5 = 0.27 moles = 1.626×10^23 molecules of HCl. We can work out the number of molecules by timesing the moles by Avogadro's constant above. Now we know the amount of molecules of HCl we have, and, since the reaction is 1:1, we need the exact same number of molecules of NaOH to neutralise it.
