Question

the molar concentration of 20 grams of NaOH solution present in 5 litres of solution is

Answer 1

5. A solution of NaOH (mw = 40) is prepared by dissolving 20 grams of the base in enough water to make one liter of solution. Calculate the molarity of this solution. the moles present in 20 gr of NaOH are: moles = gr/mw = 20/40 =0.5 moles.
