MCQ
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
  • mole fraction
  • D
    mole fraction

Answer

Correct option: 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.
