How Do You Know Which Ideal Gas Constant to Use
Where P is the pressure of the ideal gas. N is the amount of ideal gas measured in terms of moles. Ideal Gas Law Relationship Between Pressure Temperature Volume Number Of Molecules When Given Volume Temp Ideal Gas Law Chemistry Education Low Pressure The value of R depends on the units involved but is usually stated with SI. . R PV nT 101325kPa 22414L 1000mol 27315 K 8314kPa LK mol. For instance consider 1 mol of an ideal gas at standard temperature and pressure 1. Answer 1 of 4. You will choose the R value based off of the units for the known quantities in the problem. Molecules of a gas remains the same the quantity is constant for a gas regardless of the process through which the gas is taken. Look at the units for the ideal gas constant. R 8314 JmolK. PV nRT P is pressure V is volume n is the number of moles and T is temperature. R 0082 has units of L atmmol K whereas R 8314 has units of J mol K. ...
