Question

What is the molarity of NaOH in solution if 50g of an aqueous solution contains 4g of NaOH ?

Answer 1

For example, a 0.25 M NaOH solution(this is read as 0.25 molar) contains 0.25 moles of sodium hydroxide in every liter of solution. Anytime you see the abbreviation M you should immediately think of it as mol/L.
