A solution is prepared by mixing 4.32 mol of acetone with 1.45 mol of cyclohexane at 30°C. Calculate the Xacetone and Xcyclohexane in the vapor above the solution. P°acetone = 229.5 torr and P°cyclohexane = 97.6 torr.
9) A solution is composed of 1.10 mol cyclohexane (Po=97.6 torr) and 2.60 mol acetone (Po =229.5 torr). What is the total vapor pressure Ptotal above this solution?
A. If 0.420 mol of a nonvolatile nonelectrolyte are dissolved in 3.10 mol of water, what is the vapor pressure PH2O of the resulting solution? The vapor pressure of pure water is 23.8 torr at 25 ∘C . B. A solution is composed of 1.80 mol cyclohexane (P∘cy=97.6 torr) and 2.30 mol acetone (P∘ac=229.5 torr). What is the total vapor pressure Ptotal above this solution? C. As you saw in Part B, the vapor above the cyclohexane-acetone solution is composed of...
PART A If 0.720 mol of a nonvolatile nonelectrolyte are dissolved in 3.20 mol of water, what is the vapor pressure PH2O of the resulting solution? The vapor pressure of pure water is 23.8 torr at 25 ∘C . PART B A solution is composed of 1.90 mol cyclohexane (P∘cy=97.6 torr) and 2.30 mol acetone (P∘ac=229.5 torr). What is the total vapor pressure Ptotal above this solution?
A solution is prepared by mixing 44.0 g of acetone (C3H6O) and 297.2g of chloroform (CHCl3). The vapor pressures of pure acetone and pure chloroform at 35 degrees C are 345 and 293 torr. If this is an ideal solution, what is the vapor pressure, in torr, of the solution at 35 degrees C?
