Unformatted text preview: in 22.41 L at 0.0 C  9. Water is not a very good ideal gas, which is why it tends to be a liquid at STP. For water vapor, the van der Waals constants are a = 5.46 L 2 atm/mol 2 and b = 0.0305 L/mol. If water were an ideal gas, one mole of water vapor would occupy 22.41 L of volume at 273.2 K and 1.000 atm. What pressure does one mole of water vapor actually exert at this temperature, if the volume is 22.41 L?  10. . Hydrolith (CaH 2 ) reacts with water to produce hydrogen gas. How many grams of hydrolith are needed to produce 10 L of hydrogen gas at 740 mm Hg at 23 C.  11. NO(g) and O 2 (g) are separated as shown below. When the valve is opened reaction takes place to produce NO 2 (g). Determine the identity of the gas at the end of the reaction and their partial pressures. Assume that the reaction takes place at room temp. ...
