n = is the number of moles of the gas present Ru = universal gas constant [J/mol K], [lbf ft/(lb mol o R)]= 8.3145 [J/mol K]= 0.08206 [L atm/mol K] = 62.37 [L torr /mol K] T = absolute temperature [K], [ o R] For a given quantity of gas, both n and Ru are ...
The R is the ideal gas constant. The value is 0.082 atm*L/mol*K. This should be converted to different units depending on the units of other variables in the equation. How do you calculate N in PV nRT? To calculate the number of moles when all other values are known, known values ...

Solution: P = 1.0 atm, V = 1,100 L, R = 0.08206 L atm/mol L (because pressure was given as "atm" in the problem), and T = 276 K. Solve for n using the ideal gas law: (1.0 atm)(1,100 L) = n (0.08206 L atm/mol K)(276 K) ...
The form of the Ideal Gas Law in Eq. (7.3), derived from the microscopic perspective, is expressed in that equation in terms ofextensive variables. To maintain the pressure when we double the volume, we need to double the amount of gas. We may choose to express the Ideal Gas Law in ...
