When 498. mg of a certain molecular compound X are dissolved in 60.0 g of benzene (C,H), the freezing point the solution is measured to be 4.8 °C. Calculate the molar mass of X. If you need any additional information on benzene, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to the correct number of significant digits.

Calculate the molar mass (MM) of an unknown solid when 1.0 g was dissolved in 225 mL (225 g) water. The freezing point of the solution was determined to be 6.18oC.

The freezing point of a liquid will change when a solute is added. Explain how the addition of salt impacts the boiling point of water. Calculate the freezing point change for a given concentration. Given that water’s freezing point is 0.00ºC and the freezing point depression constant (Kf) is 1.86 ºC･kg/mol, calculate the freezing point depression for a 4.35 molal solution (moles/kg) of NaCl in water. Assume ideal behavior of the ions.

When 256 g of a nonvolatile, nonelectrolyte unknown were dissolved in 499 g of water, the freezing point was found to be 2.79 °C. What is the molar mass of the unknown solute?
