Example: Solving the Ideal Gas Law Equation.
The Ideal Gas Law describes the relationship between pressure, volume,
temperature, and the amount (moles) of an ideal gas:
where P is pressure (in atmospheres or N/m
number of moles of gas, R is the universal gas constant (0.0821 liter–atm/mole–K
or 8.314 J/mole–K), and T is temperature (Kelvins: K=°C + 273.1).
Enter the equation:
