7. What is the freezing point of a solution prepared from 50.0 g ethylene glycol (a nonelectrolyte, C₂H602, molar mass = 62.07 g/mol) and 85.0 g H₂O? Kr of water is 1.86°C/m. Answer: 8. An aqueous solution of a soluble compound (a nonelectrolyte) is prepared by dissolving 28.1 g of the compound in sufficient water to form 300. mL of solution. The solution has an osmotic pressure of 0.920 atm at 25.0 °C What is the molar mass (g/mL) of the compound?
