Ideal gas equation: PV = nRT | Ideal gas laws | Khan Academy The constant 'R' is there to allow for a direct relationship among the other values, (P, V, n, T). It is there to account for all the different units of measure: atmosphere, liter, mole, and kelvin. (4:12) Without a constant, one could only describe the p
PV nRT PV RT whereV Vn - NC State: WWW4 Server The big mistake you can make in a problem like this one is to get the units wrong. For example, if you forget to convert the molar mass to kilograms and plug in the number 29 instead of 0.029 then you get an answer of P = exp{ - 751}, which is essentially
Ideal gas law - Wikipedia, the free encyclopedia where P is the absolute pressure of the gas, V is the volume of the gas, n is the amount of substance of gas (measured in moles), R is the ideal, or universal, gas constant, and T is the absolute temperature of the gas. It can also be derived microscopica
