The temperature of the (near) boiling water was found to be 99.7 Co, and atmospheric pressure was 785.3 mmHg. When all of the volatile liquid was vaporized and equilibrated with the hot water the student determined that there was 1.8071 grams of vapor remaining in the flask. After filling the cleaned out flask with water and massing the system she calculated that the volume of the flask was 347.62 ml. Using the above experimental data and the Gas Constant value of 0.08206 (L x atm/ mol x K) to answer the following questions. 1. Calculate the temperature of the boiling water in Kelvins: T = Kelvins 2. Calculate the atmospheric pressure in atm: atm 3. Calculate the volume of the flask in L V= 4. Calculate the number of moles of the vaporized liquid n= moles 5. Calculate the molar mass for the liquid MM = g/mol 6. If the compound contains only Carbon and Chlorine what is the likely formula for this liquid?

In an experiment like this week's lab a student vaporized an unknown volatile liquid in a sealed flask- open to the air with just a few pinholes. The flask was placed in a boiling water bath until all of the liquid was vaporized. The temperature of the (near) boiling water was found to be 99.7 Co, and atmospheric pressure was 785.3 mmHg. When all of the volatile liquid was vaporized and equilibrated with the hot water the student determined that there was 1.8071 grams of vapor remaining in the flask. After filling the cleaned out flask with water and massing the system she calculated that the volume of the flask was 347.62 ml. Using the above experimental data and the Gas Constant value of 0.08206 (Lx atm/ mol x K) to answer the following questions. 1. Calculate the temperature of the boiling water in Kelvins: T= Kelvins 2. Calculate the atmospheric pressure in atm: P = _atm 3. Calculate the volume of the flask in L V = 4. Calculate the number of moles of the vaporized liquid n= moles 5. Calculate the molar mass for the liquid MM = g/mol 6. If the compound contains only Carbon and Chlorine what is the likely formula for this liquid?
