The vapor pressure and enthalpy of vaporization of an unknown substance are measured to be 272.9 torr and 31.5 kJ/mol, respectively at room temperature (298.15 K). Estimate the normal boiling point of the substance at an atmospheric pressure of 760 torr.
At high altitudes, the ambient air pressure can be significantly less than 1 bar, so water boils at a lower temperature than 100 C. What is the boiling point of water at an altitude where the ambient air pressure is 0.46 bar? The enthalpy of vaporization of water near its boiling point is 40.7 kJ/mol.
After swimming in a pool or lake, the air feels cool because heat is required to evaporate the water from our skin. How much heat is required to evaporate 28.8 g of water? The enthalpy of vaporization of water is 44.0 kJ/mol.
A molecule having a molar mass of 145.7 g/mol crystallizes to a cubic solid where each edge of the unit cell is 665.0 pm. Each unit cell contains 2 molecules. What is the bulk density of the crystal?
Explain why alcohols are soluble in water but hydrocarbons of the same size are not soluble in water. For example butanol is soluble but butane is not. Draw a diagram to aid in your explanation. (3 C)
