108. Solving a chemistry problem

BUT). Calculate the vapor pressure of a 20% glucose solution C6H12O6 at 25 C. The vapor pressure of water at a given temperature is 3167.73 N/m2.
B). Liquid organic matter, practically insoluble in water, was distilled with steam under normal atmospheric pressure at 98.4 C. The content of organic liquid in the condensate was 23.1 wt.%. Determine the molar mass of the substance and its vapor pressure at the specified temperature, if the saturated vapor pressure of water under these conditions is 958.65 N/m2.
