Unformatted text preview: of the flask to hold .155 liters. Using the given barometric pressure (765 mmHg), I was able to calculate the molecular weight for each experiment. I calculated them to be 92.25 g/mol and 101.77 g/mol, an average of 97.01 g/mol. Conclusion We were able to find these calculations because of how easily measurable the physical properties of this lab were. The pressure of the vapor was just the atmospheric pressure as the flask was left open to the atmosphere. The temperature is the temperature of the boiling water. The mass was the difference in mass of the empty flask and the vapor filled flask. Care must be taken to be accurate as possible, as this could create a large margin of error....
