Prepare For It! Prelab Question A student weighs a flask, foil cover, and rubber band and finds the mass is 74.95 g. He then adds about 5 mL to the flask and then heats the flask in a boiling water bath (100.0°C) to evaporate all of the volatile liquid. Once the flask is removed from the water bath and cooled, the collected gas condenses into a liquid. The mass of the flask, foil cover, rubber band, and condensed liquid is...

MST SHOW ALL CALCULATIONSs. Please be neat. Use correct significant figures. 1. 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...

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.

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...
