Question

1. A sample of an ideal gas has a volume of 2.26 L at 278 K and 1.10 atm. Calculate the pressure when the volume is 1.80 L and the temperature is 303 K.

2. The volume of a sample of hydrogen gas was decreased from 10.76 L to 4.05 L at constant temperature. If the final pressure exerted by the hydrogen gas sample was 8.39 atm, what pressure did the hydrogen gas exert before its volume was decreased?

3. If the partial pressure of the diatomic gas is 0.780 atm, what is the total pressure?

4.  A mixture of He, Ne, and Ar has a pressure of 21.2 atm at 28.0 °C. If the partial pressure of He is 1.73 atm and that of Ar is 1.06 atm, what is the partial pressure of Ne?

Answer 1

ideal qag equation z - T, 1.80 2. = 1.505 atm 2) faomh idealaas equatior Pax lo-K = 3.39 x 4.05 8.39% 4.05-3.1579 atm 10.
