Biphenyl, C,,H10, is a nonvolatile, nonionizing solute that is soluble in benzene, C,H,. At 25 °C, the vapor pressure of pure benzene is 100.84 Torr. What is the vapor pressure of a solution made from dissolving 14.4 g of biphenyl in 29.2 g of benzene? Psolution Torr

When 2.85 g of a certain molecular compound X are dissolved in 85. g of dibenzyl ether ((CH₂CH₂)₂O), the freezing point of the solution is measured to be 2 -1.2 °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 the correct number of significant digits. X x10 Ś

Biphenyl, C12H10, is a nonvolatile, nonionizing solute that is soluble in benzene, C6H6. At 25 ∘C, the vapor pressure of pure benzene is 100.84 Torr. What is the vapor pressure of a solution made from dissolving 11.4 g of biphenyl in 33.4 g of benzene?

A solution is made by mixing 72.1 grams of propyl chloride, C3H7Cl, and 38.4 grams of propyl bromide, C3H7Br.  What is the vapor pressure of propyl chloride in teh solution at 25 degrees C?  Assume that the solution is an ideal solution.  The vapor pressure of pure propyl chloride is 347 torr at 25 deg C and of pure propyl bromide is 133 torr at 25 deg C.   - Thanks - need help!  I've worked this out for my quiz several times and cannot come up with the correct answer.  Heather (middle name).
