an ideal gas is enclosed in a container of volume V at pressure p. It is being pumped out of the container by using a pump with stroke volume v. what is the final pressure in the container after n stroke of the pump?

Hmm let's see...I forgot how to do this but let me try..

before: P, V
after n-stroke: $\sf P_f, V-nv$
Temperature constant: PV=constant
ideal gas equation is PV=vRT
so $\sf PV= P_f(V-nv)$
then...
manipulate... manipulate...
that will be.....$\sf \large P_f=\frac{PV}{V-nv}$

ta-da! :)
