Which of the following indicates the mathematical expressions for Dalton's law of partial pressures
a) Partial pressure = $\frac{\mathrm{The} \mathrm{component} \mathrm{gas} \mathrm{volume}}{\mathrm{Total} \mathrm{volume}}$ x Total 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
