Part A) An organic chemist isolates a colorless liquid from a petroleum sample. She places the liquid in a pre-weighed flask and puts the flask in boiling water, which vaporizes the liquid and fills the flask with gas. She closes the flask and reweighs it. She obtains the following data: Volume (V) of flask = 121 ml T = 99°C P= 798 mmHg mass of flask + gas = 81.8 g mass of flask = 78.8 g Calculate the molar mass (in g/mol) of the liquid. Enter to 1 decimal place. Part B) 157 ml of hydrogen gas, measured at 22°C and 2.8 atm pressure, and 279 ml of nitrogen gas, measured at 22°C and 2.6 atm pressure, were forced into the 157 ml container at 22°C, what would be the pressure of the mixture of gases now in the 157 ml container? Enter to 2 decimal places.
