PV = mRT is the original form of the ideal gas law that can be used to find the lift of a hot air balloon or the mass of air contained in a room. The universal gas constant If the equation is rewritten as PV = nRT where n is the number of moles of gas enclosed (directly related to the mass m) then the gas constant takes a valu The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. If you use this value of R, then technically the formula should be written as pV = mRT, where m represents the mass of air in kg (and we avoid having to do any calculations with moles. PV = mRT (1) is another form of the familiar PV = nRT (2). Here, n = no. of moles of gas = mass of gas/molecular weight of gas = m/M. So, (R in (1)) = (R in (2))/M. The R in (1) is called specific gas constant and has units of J/(g.K). The R in (2) is called universal gas constant and has units of J/(mol.K). In essence, they both are the same
