Understanding
The ideal gas law relates pressure, volume, moles, and temperature for an ideal gas. Use R = 0.082057 L·atm/(mol·K) when pressure is in atm, volume is in liters, and temperature is in kelvin.
FAQs
What is R in the ideal gas law?
When using atm, liters, moles, and kelvin, R = 0.082057 L·atm/(mol·K).
Does temperature need to be in kelvin?
Yes. Ideal gas law calculations should use absolute temperature in kelvin.
