Which solution has a higher vapor pressure, 1 M NaCl or 1 M glucose(C6H12O6)?

Answer 1

I worked the osmotic pressure almost to completion for you. This one I'll get you started and let you finish.
P_soln = X_solvent*P^o_solvent

I wonder if you intended to write 1 M or 1 m; i.e., 1 molar or 1 molal.
