@X@user.full_name@X@ @GMU: How much work has been done when the volume of a gas changes from 19.28 L to 13.79 L at a constant pressure of 1.849 atm and temperature?

@X@user.full_name@X@ @GMU: Assume you have an open ended manometer filled with an oil having a density of 0.7791 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure in atmospheres if the level of the arm open to the atmosphere is 134.78 cm higher than the level in the arm connected to the gas sample? The atmospheric pressure reading is 758.94 mm Hg.

@X@user.full_name@X@ @GMU: Draw the lewis dot structure of SO2. How many lone-pairs of electrons (first) and bonding pairs of electrons exist on the molecule SO2?

@X@user.full_name@X@ @GMU: A gas mixture contained 33.69% by weight HCN and 66.31% N2O4. What was the mole fraction of HCN?

@X@user.full_name@X@ @GMU: A flexible container was filled with CO2 gas at a pressure of 1.118 atm and volume of 12.829 L. What volume would this same gas occupy if the pressure increased to 2.275 atm? Assume temperature is constant.
