Serway & Jewett — The Kinetic Theory of Gases: Problem 7.

In a period of $1.00\text{ s}$, $5.00 \times 10^{23}$ nitrogen molecules strike a wall with an area of $8.00\text{ cm}^2$. Assume the molecules move with a speed of $300\text{ m/s}$ and strike the wall head-on in elastic collisions. What is the pressure exerted on the wall? Note: The mass of one $\text{N}_2$ molecule is $4.65 \times 10^{-26}\text{ kg}$.
