A few milliliters of an Post by: chemDO on Jan 24, 2016 A 255 mL round-bottom flask is weighed and found to have a mass of 114.85 g. A few milliliters of an easily vaporized liquid are added to the flask and the flask is immersed in a boiling water bath. All of the liquid vaporizes at the boiling temperature of water, filling the flask with vapor. When all of the liquid has vaporized, the flask is removed from the bath, cooled, dried, and reweighed. The new mass of the flask and the condensed vapor is 115.23 g. Which of the following compounds could the liquid be? (Assume the ambient pressure is 1 atm.)
A) C4H10 B) C2H5OH C) C3H7OH D) C4H9OH E) C2H6 Title: Re: A 255 mL round-bottom flask is weighed and found to have a mass of 114.85 g. A few milliliters o Post by: shutchka on Jan 28, 2016 Content hidden
