What is the equation of the ideal gas law?
The equation is PV = nRT?
Where the pressure - P, is in atmospheres (atm) the volume - V, is in liters (L) the moles -n, are in moles (m) and Temperature -T is in Kelvin (K) as in all gas law calculations.
When we do the algebraic reconfiguration we end up with Pressure and Volume being decided by moles and Temperature, giving us a combined unit of
If you choose not to have your students work in standard pressure unit factor, you may also use: 8.31
Temperature must always be in Kelvin (K) to avoid using 0 C and getting no solution when students divide.
Where M is the Molar Mass in
Pressure and Temperature must remain in the units atm and K and the Gas Law Constant remains R = 0.0821
I hope this is helpful.
