hi, can someone answer this question for me? The triple point of carbon dioxide is p=518500 Pa, T=216.58 K, and its molar enthalpy of sublimation is 26.1 kJ mol-1. Calculate the sublimation temperature, expressed in K and correct to 2 decimal places, of carbon dioxide at a pressure of 441 kPa.

1. The normal boiling point of benzene (i.e., at 1 atm) is 80.09 °C. The molar enthalpy of vaporization is 30.72 kJ mol . Assuming that AvapHm and AvapSm stay constant at their values at 80.09°C, calculate the values of AvapGm at 75.0 °C, 80.09 °C and 85.0 °C. Given your calculated values, do you still expect benzene to spontaneously condense at 75.0 °C and to spontaneously evaporate at 85.0°C? -1 2. The vapor pressure of a liquid was measured...

A student masses an empty flask, aluminum foil (witha small pinhole), and copper wire and finds the mass to be 54.8680 g. She then adds about 5.0 mL of an unknown liquid and heats the flask in a hot waterbath to 95.0 °C. After all the liquid is vaporized, she removes the flask from the bath and masses it after it has cooled. The mass...
