Self-Practice problems
1. Consider 4 moles of gas at a pressure of 5.6 atm and a volume of 12 liters. What is the temperature of the system?
2. If a pressure in the system is 1.2 atm, its volume is 31 L and the temperature is 87° C, what amount of gas is present in the system?
3. If 3 moles of gas occupy a container with volume of 60 L at temperature of 400° K, what pressure would the system experience?
4. What volume would 5 moles of carbon dioxide occupy in standard conditions?
5. What is a density of the system that contains 5 moles of Carbon Dioxide, considering standard conditions?
6. If the gas that was contained in a vessel at 1 atm and occupied 2 L, was allowed to expand into the bigger vessel (total system volume is 12 L), what will be a pressure in this system?
7. How would the temperature change if a gas that was contained in 1 L vessel at 25 K was allowed to expand to a volume of 100 L?
8. Consider a 100 L of gaseous mixture that is consists of 21 L of oxygen and 79 L of nitrogen. What are the partial pressures of O2 and N2 in this mixture? What is total pressure of the system? Consider that the system is in standard conditions.
