What does Dalton's law of partial pressure state?

Options

  1. AThe total pressure is always greater than the sum of the partial pressures.
  2. BThe total pressure is less than the sum of the partial pressures.
  3. CThe total pressure is equal to the sum of the partial pressures.
  4. DThe total pressure is unrelated to the partial pressures.

Correct answer

C. The total pressure is equal to the sum of the partial pressures.

Step-by-step solution

Dalton's law of partial pressure states that the total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.
