1. If you place 10.0 L of methanol (CH4O) in a sealed room that is 3 m long, 1.75 m wide, and 2.5 m high, will all the methanol evaporate? If some liquid remains, how much will there be? The vapor pressure of methanol is 127 torr at 25 °C, and the density of the liquid at this temperature is 0.791 g/mL. Treat the room dimensions as exact numbers.
The answer should be in L

Two 1-L beakers, A and B, each containing a different aqueous solution of urea (a nonvolatile nonelectrolyte with MW = 60.06 g/mol) are placed together in a box, which is then sealed. The temperature remains constant at 20 °C. Initially, there is 270 mL of solution in A and 690 mL of solution in B. As the solutions stand in the sealed box, their volumes change slowly for a while. When they stop changing, beaker A contains 490 mL and...
