What is the freezing point of a solution containing 3.10 grams of benzene (molar mass = 78.0 g/mol) dissolved in 32.0 grams of paradichlorobenzene?

5 L山 When 1.06 g of a certain molecular compound X are dissolved in 85.0 g of dibenzyl ether ((C,H,CH,),0), the freezing point of the solution is measured to be 0.9°C. Calculate the molar mass of X. If you need any additional information on dibenzyl ether, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to 1 significant digit. 自 OL Check Save For Later Submit Assignment O2022 McGraw Hill LLC. AlI Rights Reserved.

Find the freezing point of a solution obtained by dissolving 4.71 g of the aminoacid alanine (a molecular compound with molecular formula C3H7NO2 and molar mass = 89.09 g/mol) in 174 g of benzene. The melting point of pure benzene is 5.5 °C and the freezing point depression constant of benzene is 5.12 °C/m. Give the answer with 2 or more significant figures.

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?

Omotic Pressure is a technique used to find the length of a polymer using its Molar Mass. If a 32.25 mg sample of PVC (polyvinyl chloride) is dissolved in benzene to 25.00 mL total solution at 30.00 oC, its osmotic pressure is 7.268 mm Hg. What is the Molar mass of the PVC?​​ = i MRT​760 mm Hg = 1.00 atm​R = 0.08206 L-atm / mol K ​
