Imagine that you have an ideal gas in a 6.60 L container, and that 2750 molecules of this gas collide with a square-inch area of the container at any given instant. If the volume is increased to 26.4 L at constant temperature, how many collisions will occur per square inch of this larger container?

No because it not possibly

Sorry i dont understand the question can you rephase it?

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
