Which of the following indicates the mathematical expressions for the Dalton's law of partial pressures

a) Partial pressure = $\frac{\mathrm{The} \mathrm{component} \mathrm{gas} \mathrm{volume}}{\mathrm{Total} \mathrm{volume}}\times \mathrm{Total} \mathrm{pressure}$

b) Partial pressure = mole fraction of component gas × Total pressure

c) Partial pressure = Partial volume × Total pressure

d) Partial pressure = No. of moles of component gas × Total pressure

Given data: Dalton's law of partial pressures

Concepts used: Dalton's law

Detailed solution:

According to Dalton's law 

Partial pressure is equal to the rate of component gas volume to the total volume.

Partial pressure also equals to the product of mole fraction of component gas and total pressure.

The ratio of partial pressure to the total pressure is equal to partial volume.

So, here the correct option is D
