How many ml of 5.0 M NaOH do I need to get 39.0 g of NaOH

DrBob222 · Answer

I can't tell if that is 4.1 L or you have the solute dissolved in four(4) 1L containers.
Osmolarity = # moles solute particles/L soln.
# moles solute particles is (278/molar mass NaCl)*2/L soln. Subtitute whatever the correct value is for the volume of solution.
