Enthanol C2H5OH melts at -114 degrees Celsius. The enthaply of fusion is 5.02 kl/mol. The specific heat of solid as well as liguid ethanol is 0.9701 J/gK and 2.30 J/gK, respectively. Explain how much heat (in kj) is needed to convert 25.0 g of solid ethanol at -135 degrees Celsius to liquid ethanol at 25.0 degree Celsius?
The vapor pressure of pure methanol, CH3OH, at 30 °C is 160. torr. How many grams of the nonvolatile solute glycerol, C3H5(OH)3, must be added to 131. g of methanol to obtain a solution with a vapor pressure of 133. torr?
The below table lists pressure and volume measurements for air in a cylindrical piston of an air compressor. The variables may be assumed related
