Dalton's Law: Partial Pressure (Simplified) Practice Problems

A 500 mL vessel contains a mixture of neon gas and chlorine gas (Cl₂). The total pressure of the mixture at 28.0°C is 745 mmHg. Calculate the partial pressure of chlorine if neon has a partial pressure of 148 mmHg.

Consider a mixture consisting of argon gas and nitrogen gas. Assuming that the partial pressures and the volume of the gases at a certain temperature are the same, compare the number of argon atoms and nitrogen molecules.

In interstitial lung disease, oxygen is inefficiently transferred into the capillary space, leading to the decreased partial pressure of oxygen in the blood. Why does a person with interstitial lung disease use a portable oxygen delivery service?

Hypoxemia is caused by reduced oxygen in the blood or restricted blood flow. Which of the following describes what happens to the partial pressure of oxygen in the blood?

Consider a tank containing a mixture of gases. Calculate the total pressure (in mmHg) of the mixture if it consists of nitrogen gas at 380 Torr, oxygen gas at 1.4 atm, and helium gas at 380 mmHg.

Which of the following correctly describes the partial pressure of a gas?

What are the percent compositions of each gas in a vessel at 34°C and 1.50 atm if the vessel contains the following: P_He = 655 mmHg, P_Xe = 194 mmHg, P_Ar = 120 mmHg, and P_Kr = 171 mmHg?

Consider a specific reaction with ΔH° = 66.8 kJ/mol and ΔS° = 105.3 J/mol•K. Assuming that these values do not change with temperature, at what temperature range is the reaction spontaneous in the forward direction?

The reaction is spontaneous for temperatures (less than, greater than) T = ________ K.

A 285 mL flask contains a mixture of CO, CO₂, and O₂ at 15°C. What is the partial pressure of O₂ if the total pressure is 795 torr, the CO has a partial pressure of 265 torr and the CO₂ has a partial pressure of 355 torr?

Consider a sample of gas of equal parts in moles of hydrogen and argon is stored in a sealed container at room temperature. Which gas has a higher partial pressure?  

Calculate the partial pressure of H₂ in a 350 L vessel that contains 1.08 g of H ₂, 53.8 g CO_2, and 37.7 g of O₂ at 25°C
