APFIVE Ideal Gas Law And Stoichiometry
All of the following statements regarding the application of the ideal gas law in stoichiometry calculations are true except:
Gas Law Constant
$$R = 0.0821\,L*atm/(mol*K)$$
A
The ideal gas law relates pressure, volume, temperature, and number of moles for a gaseous system.
B
When conditions deviate from STP, the ideal gas law, $$PV=nRT$$, must be used to determine the number of moles.
C
Using the molar volume of $$22.4\,L/mol$$ is accurate for gases under any conditions, even if not at STP.
D
At STP, one mole of an ideal gas occupies $$22.4\,L$$, providing a useful conversion factor.
