## Homework Statement

An ideal gas is in a container at temperture 300 degrees. What fraction of its moelcules will have speeds in the range 1.95v and 2.05v where v is the most probable molecular speed?

Assume dN is constant in the range around 2v

## Homework Equations

Maxwell velocity distribution (MVD)

## The Attempt at a Solution

The answer should be in the form of dN/N

dN/(.1v)=MVD so dN can be worked out. But how do you work out N?
