(Willow '21) A solution of 0.500 g of an unknown nonvolatile, nonelectrolyte solute is added to 100. mL of water and then placed across a semipermeable membrane from a volume of pure water. When the system reaches equilibrium, the solution compartment is elevated 5.60 cm above the solvent compartment. Assuming that the density of the solution is 1.0 g/mL, calculate the molecular mass of the unknown
