Partial Pressure

#### Q. Oxygen gas (O2), nitrogen gas (N2), water vapor (H2O) and carbon dioxide gas (CO2) occupy the same container. The total pressure in the container is 2 atm. The mixture of the gases is 12% O2, 54% N2 and 15% H2 What is the partial pressure of Oxygen gas (O2), nitrogen gas (N2), water vapor (H2O) and carbon dioxide gas (CO2) in the container? What gas law did you use to solve this problem?

Partial Pressure

#### Q. A mixture of CS2(g) and excess O2(g) is placed in a 10 L reaction vessel at 100.0 °C and a pressure of 3.10 atm. A spark causes the CS2 to ignite, burning it completely, according to the equation: CS2(g) + 3 O2(g) → CO2(g) + 2 SO2(g) After reaction, the temperature returns to 100.0 °C, and the mixture of product gases (CO2, SO2, and unreacted O2) is found to have a pressure of 2.45 atm. What is the partial pressure of each gas in the product mixture? Enter your answers numerically separated by commas.
