Question 4 At 35 °C, the vapor pressure of pure ethanol is 103.3 torr. A solution is prepared by dissolving 65.0 g of the nonvolatile molecular solute ethylene glycol (C₂H6O2, molar mass = 62.07 g/mol) in 225.0 g of ethanol (C₂H5OH, molar mass = 46.07 g/mol). Find the vapor pressure lowering compared to pure ethanol. O 18.2 torr 22.1 torr 10.8 torr O 23.2 torr 1 pts O 29.8 torr
At 25.00 °C the vapor pressure of pure hexane is 151.2 torr, and that of pure heptane is 45.6 torr. What is the mole fraction of hexane in the gas phase above a solution containing 4.898 mol of liquid hexane and 4.749 mol of liquid heptane at 25.00 °C?
A solution containing 100.0 g of unknown liquid and 900.0 g water has a freezing point of -3.33 °C. What is the molar mass of the unknown liquid? K(H₂O)=1.86 °C/m, Tr°(H2O) = 0.0 °C. O 619 g/mol O 17.2 g/mol O 161 g/mol O 62.1 g/mol O333 g/mol
(heptanol), Consider three alcohols: CH3CH₂CH₂CH₂CH₂CH₂CH₂OH CH3CH₂CH₂CH₂CH₂OH (pentanol) and CH3CH₂CH₂OH (propanol). Arrange the three alcohols in order of increasing solubility in water. The least soluble should be given first and the most soluble last. O heptanol propanol < pentanol O pentanol heptanol <propanol propanol pentanol < heptanol heptanol pentanol < propanol propanol heptanol < pentanol
