A solution is prepared by dissolving 25.0 g of glucose, C6H12O6, in 125 g of water at 25oC. (show work please)
Determine the freezing point of the solution.
mols sucrose = grams/molar mass
solve for mols.
molality = m = mols/kg solvent
solve for m
dT = Kf*m
solve for dT and subtract from 0.
A solution is made by dissolving 50.0 g of glucose (C6H12O6) with 600.0 g of water. What is the vapor pressure of this solution at 80.0℃? (nonvolatile)
