A 5 mL sample of an unknown liquid is placed into a 250 mL flask that has had all of the air removed. The pressure measured in the flask is found to be 39.4 kPa. In a seperate trial the student puts 214 mL of the same liquid into the same flask at the same conditions. What will the pressure measure (in kPa) in the second trial? I have tried P1V1 = P2V2 and got the answer P2=268 kPa, but...

An empty 149 mL flask weighs 68.322 g before a sample of volatile liquid is added. The flask is then placed In a hot (95.0 degree C) water bath; the barometric pressure is 740 mm Hg. The liquid vaporizes and the gas fills the flask. After cooling the flask and condensed liquid together weigh 68.697 g. What is the molar mass of the volatile liquid? 9.73g/mol 78.09 g/mol 4.80 times 10^-3 g/mol 49.69/mol 44.01 g/mol

Chame nsead tu age 06-17 Experiment 8: Molar Mass of a Volatile Liquid Purpose To determine the molar mass of a pure substance we need to find out (a) the number of moles in a given sample, and (b) the mass of the same sample. Molar mass is then: mass divided by moles Introduction Using the ideal gas equation, PV= nRT, we can determine the number of moles (n) of gas or vapor under measured conditions of pressure (P), volume...
