the **Ideal Gas Law** is the mathematical relationship among pressure, volume, temperature, and moles. Sample Problem: What is the pressure in atm exerted by a 0.500 mole sample of nitrogen gas in a 10.0 L container at 298 K?  Given: V of N2 = 10.0 L   N of N2 = 0.500 mole T of N2 = 298 K  Unknown: P of N2    PV = nRT P= __nRT__ V     (__0.0821 L__  __ ·  __ __ atm __ ) P = __(0.500 mole) (mole__ __ ·  __ __ K) (298 K) __ 1.22 atm 10.0 L main page !!
 * The Ideal Gas L a  w  **
 * The ideal gas law has an equation which shows the relationship between pressure, volume, temperature, and the number of moles of the gas. This equation looks like: PV=nRT
 * This boils down to Boyle’s equation, the others only work when certain things are constant.
 * If the temperature goes up, the pressure will as well, and vice versa.
 * The R in the above equation represents the **ideal gas constant**.
 * The value of R is usually rounded to .0821 L  · atm, or mole  ·  K. when the temperature is in Kelvins, pressure in atmospheres and volume in Liters, this works.
