If 650 mL of water instead of 500mL were used to dissolvethe

If 65.0 mL of water (instead of 50.0mL) were used to dissolvethe potassium hydrogen phthalate, would the calculated molarity of the NaOH solution be less, greater or remain the same? Explain

Solution

remains same,
though molarity of pthalate is decreased. no. of moles in the solution remains same. since reaction proceeds based on mole to mole ratio, NaOH molatiy remains same.
