Question

In a given mixture of non-reacting gases, the ratio of partial pressure of each gas is equal to its:

• A. weight percent
• B. volume percent
• C. mole fraction
• D. critical pressure

Answer 1

The correct option is C mole fraction

Dalton's law of partial pressures states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases. The ratio of partial pressure of a gas to the total pressure is equal to the mole fraction of the gas.
