40 ml of NaOH contains 0.04 L * 3.5 M = 0.14 mole of NaOH
Since NaOH donates 1 OH you will also have 0.14 mole of OH- in solution.
This can be neutralised with an equal amount of H+.
HCl can donate 1 H+, so you need an equal amount of H+ to neutralise the OH-.
So you need 0.14 mole of the HCl.
55 ml has 0.14 mole HCl.
So the molarity is: 0.14 mole / 0.055 L = 2.54 M

How many grams of solid NaOH are needed to prepare 500mL NaOH solution with a concentration of 0.4M?
molarity equals moles of solute /volume of solution in litres . moles of NaOH equals 5g/40g = 0.125 and volume of solution will be volume of water + volume of NaOH = 0.5 litre+0.002 l which is nearly 0.5 litre . (volume of NaOH is calculated by its density) so molarity = 0.125mol/0.5litre = 0.25 M
