Say, we have 1 molar solution of $\ce{NaCl}$ and 1 molal solution of $\ce{NaCl}$. Among these, which will have maximum vapour pressure?

I know that vapour pressure will depend on the number of $\ce{Na+}$ and $\ce{Cl-}$ ions, but how do we determine which has greater amount? Like one is 1 mol in 1 L while other is in 1 kg.
