As a general rule, there's relatively more solute and less solvent in a 1 molar solution than a 1 molal solution, so it'll have more mass if the solute has more mass than the solvent, a good bet. The difference, obviously, is in normal circumstances tiny enough that only your chemistry teacher will care.
