In short just use algebra to get the equation below Start with
[P + a*(n/V)^2] * (V - nb) = nRT which is the standard Van Der Waals equation and solve for n using algebra. which gives the 3rd order equation below. -(ab/V^2)*n^3 + (a/V)*n^2 - (bP+RT)*n + PV = 0 The simplest way to solve this equation is to enter it into Excel and graph it with multible values of n from 0 to whatever gets you to zero. The value that gives you zero is the answer. Be sure you use all the proper units for the other varables. Hope this helps.
Van der Waals forces, Apex
You can use van der Waals forces to explain the differences in boiling points, etc. for various compounds.
Hydrogen bonding. Perhaps Van der Waal's forces could be included as weak bonds.
Maybe Van Der Waals interactions?

you don't solve for a, a is a value that's given in a table...you just find it in your text book or somethng,it gives you the value of a for the specific real gas you're working with.
i dont know but still you are not answering me.why?
The Nobel Prize in Physics 1910 was awarded to Johannes Diderik van der Waals for his work on the equation of state for gases and liquids.

Yes, most probably Van der Waals interactions
They are named after Johannes Diderik van der Waals who was the first to postulate about inter molecular forces
Hydrogen bonds are the reason for cohesion and Van Der Waals equation is the cause of adhesion.
Johannes Diderik van der Waals died on March 8, 1923 at the age of 85.
