faizan Posted August 7, 2008 Share Posted August 7, 2008 Which one is more concentrated 1 molar solution of NaOH or 1 molal solution of NaOH? Link to comment Share on other sites More sharing options...
ecoli Posted August 7, 2008 Share Posted August 7, 2008 its about the same if its in water. Molarity is moles/L and molality is moles/Kg. At STP 1 L of water is approximately equal to 1 kg. Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted August 7, 2008 Share Posted August 7, 2008 They're pretty much equivalent. Molarity is moles/liter, and molality moles/kg, and the density of water roughly 1kg/L. That makes them very close to being identical. Link to comment Share on other sites More sharing options...
