Which law relates the partial pressure of a gas to the total pressure of a gas mixture?

• A. Boyle's Law
• B. Dalton's Law of Partial Pressures
• C. Avogadro's Law
• D. Charles's Law

Answer: (B)

Verified step by step guidance

1. Understand that the problem is asking about the relationship between the partial pressure of a gas and the total pressure in a gas mixture.
2. Recall that Boyle's Law relates pressure and volume of a gas at constant temperature, not partial pressures in mixtures.
3. Recall that Charles's Law relates volume and temperature of a gas at constant pressure, also not about partial pressures.
4. Recall that Avogadro's Law relates volume and number of moles of gas at constant temperature and pressure, again not about partial pressures.
5. Identify that Dalton's Law of Partial Pressures states that the total pressure of a gas mixture is the sum of the partial pressures of each individual gas, which directly relates partial pressures to total pressure.
