The mole fractions of a gas multiplied by the total pressure of the mixture are called_of a gas.
Correct answer: B. Partial pressure
- A. Partial volume
- B. Partial pressure
- C. Partial temperature
- D. Number of moles
Explanation
Option A: The actual volume occupied by one species of molecule or particle in a solution. Option B: The pressure exerted by components in a mixture of gases. Option C: A system with a hotter temperature tends to lose heat to a system with a colder temperature. Option D: A mole is the amount (10) of material containing 6.02214 × 1023 particles. 1 mol = 6.02214 × 1023 particles. This number is also called Avogadro's number. Notice that the definition of the mole is an amount of substance.

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
