Unformatted text preview: using (a) the ideal gas equation and (b) the van der Waals equation. (For neon, a= 0.211 atm.L^2/mol^2 and b= 0.0171 L/mol.) 7. What pressure (in atm) is exerted by a column of isopropanol (C3H7OH) 275 m high? The density of isopropanol is 0.785 g/cm^3. 8. A 2.77 L flask at 1 degree C contains a misture od N2, He, and Ne at partial pressures of 0.301 atm for N2, 0.167 atm for He, and 0.391 atm for Ne. a. Calculate the total pressure of the mixture. b. Calculate the volume in liters at STP occupied by He and Ne if the N2 is removed selectively. 10. What pressure would be required for Helium at 25 degree celcius to have the same density as argon at 25 degree celcius and 1.00 atm? 11. Calculate the density of helium in a helium balloon at 15.1 degree celcius. (Assume that the pressure inside the balloon is 1.07 atm.)...
