Sodium hydroxide is extremely soluble in water. At a certain temperature, a saturated solution contains 567 g of NaOH (s) per liter of solution. Calculate the molarity of this saturated NaOH (aq) solution

14.2M

Explanation:

Amount = Concentration * Volume

But volume is 1 litre as stated in the question

And amount = mass / molar mass

Molar mass of NaOH = 23+16+1=40gmol-1

Amount of NaOH = 567/40=14.2moles

But concentration = amount/volume

Hence molarity = 14.2/1 = 14.2M
