The boiling point of benzene, C6H6 , is 80.100 °C at 1 atmosphere. Kb (benzene)= 2.53C/m. In a laboratory experiment, students synthesized a new compound and found that when 14.93 grams of the compound were dissolved in 252.2 grams of benzene, the solution began to boil at 80.619 °C. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound?   The freezing point of ethanol, CH3CH2OH, is -117.300 °C at 1 atmosphere. Kf(ethanol) = 1.99 °C/m. In a laboratory experiment, students synthesized a new compound and found that when 12.91 grams of the compound were dissolved in 271.5 grams of ethanol, the solution began to freeze at -117.406 °C. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound?

What is the hydration state of CuSO4. x -H2O? Mass of sample: 1.000 (g)  Mass of water lost: 0.361 (g)

Under normal conditions, the human adrenal medulla secretes epinephrine (C9H13NO3) at a rate sufficient to maintain a concentration of 10−10 M in circulating blood. To appreciate what that concentration means, calculate the volume of water that you would need to dissolve 1.0 g (about 1 teaspoon) of epinephrine to a concentration equal to that in blood.

What is the approximate concentration of sodium ions in a 0.10 M Na2CO3 solution? Assuming ideal behavior, what is the boiling point of a solution of 9.04 g of nonvolatile I2 in 75.5 g of benzene?  (For benzene, Tb = 80.1oC and Kb = 2.53 oC/m) Assuming ideal solution behavior, what is the molar mass (g/mol) of a nonelectrolyte compound if a solution of 5.00 g of the compound in 25.00 g of carbon tetrachloride boils at 81.5 °C at 1 atm?  (For carbon tetrachloride Tb = 76.8 °C; kb = 5.02 °C/m)
