Molarity and Molality

[faizan]

Which one is more concentrated 1 molar solution of NaOH or 1 molal solution of NaOH?

[ecoli]

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.

[Cap'n Refsmmat]

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.
