How many grams and moles of glucose, C6H12O6, should be dissolved in 250 mL of solution to make a solution with an osmotic pressure of 12.3 atm at 27 °C? If 0.0125 moles of nonelectrolyte are dissolved in 125 grams of benzene (solvent), freezing temperature of the solution is lowered by 0.512°. What is cryoscopic constant of benzene?
