Question

1. A 4.00 L flask at 25.0 degrees C contains Argon at a partial pressure of 0.0850 atmosphere. What would be the partial pressure of Argon after we add 1.00 g of Argon gas to the flask without changing the temperature or volume?

2. A 922 mL sample of CH4 gas at 641 torr and a temperature of 125.00 degrees C is compressed at constant temperature to 325 mL. Predict the pressure of the CH4 after this process. (Answer should be in torr)

3. A sample of gas held at constant volume of 5.00 L is cooled from 228 degrees C to -75.0 degrees C. The initial pressure is 805 mmHg. Predict the new pressure.

4. A sample of hydrogen gas was collected over water at 20 degrees C. The toal pressure of gas is 685.0 mmHg. Calculate the partial pressure of H2(g) in atmospheres.

5. What quantity is inversely proportional to the pressure of gas?

A. Speed

B. Atomic mass

C. Volume of gas

D. Formula mass
