Please help with these two
1. A flask is filled with 1.08 moles of a gas at 20.7 K and
646.8 mm Hg. The flask is then opened and an additional 1.33 moles
are added. The temperature of the flask is then changed to 272.4 K.
What is the pressure (in atm) of the flask under these final
conditions?
2. The density of a gas is 4.22 g/L at a pressure of 1.77 atm
and a temperature of 14.66 °C. What...
