#"The partial pressure is the pressure exerted...."#

Explanation:

#"The partial pressure is the pressure exerted by a component, A,"#
#"in a gaseous mixture. " P_A" is the same as the pressure it would"# #"exert if it ALONE occupied the container."#

And thus #P_"total"=P_A+P_B+P_C.........#

If we assume ideality, then #P_"Total"=(n_"Total"RT)/V#

#=(n_1+n_2+n_3.....)xx(RT)/V#

And thus the #"partial pressure"# is proportional to its molar quantity.
