lan418 Posted November 26, 2005 Share Posted November 26, 2005 I've been working on these problems for some time. However, i havent been able to rationalize the answer for the following problems. 1. A 95.0 mL sample of He(g) is collected over water at 765 Torr and 56 degrees C. If, at these conditions, the "dry" V of this He(g) sample is 79.6 mL, the VP of water at 56 degrees C is closest to 1. 94.5 torr 2. 46.9 torr 3. 79.5 torr 4. 153.3 torr 5. 123. 8 torr 2. If water is saturated with a mixture of N2 (g) and a second gas at STP to give a solution which freezes at -0.00184 degrees X, and x(greek letter symbol chi) = 0.45 for N2 (g) above the water, the Henry's constant for the second gas is closest to 1. 9.6 x 10 E-4 mol/L atm 2. 2.2 x 10 e-3 mol/L atm 3. 5.5 x 10E-4 mol/L atm 4. 2.6 x 10 E -3 mol/L atm 5. 1.7 X10 e-3 mol/L atm 3. If a sample of an ideal gas in a closed flask exerts a P(pressure) of 560 torr at 125 degrees X and a P of 960 torr at 250 degrees X and T in degrees X varies linearly as a function of Delta P, absolute zero in degrees X is closest to 1. -125 degrees X 2. -25 degrees X 3. -75 degrees X 4. -100 degrees X 5. 50 degrees X Link to comment Share on other sites More sharing options...
insane_alien Posted November 28, 2005 Share Posted November 28, 2005 1. PV=nRT and then Pt = PP1+PP2+..+PPn 2.no idea 3. PV=nRT hope you didn't expect me to give you the answers Link to comment Share on other sites More sharing options...
lan418 Posted November 30, 2005 Author Share Posted November 30, 2005 Nope. Your suggustions won't work. Link to comment Share on other sites More sharing options...
