    Why do you think there's a difference? Isn't it just the universal gas constant in both cases?

    Is Bolye's law's Ra equal to the R in the PV=NRT?
    Bolye's law is PV = RaT

    Sorry, but that's gibberish. Read more carefully what is done.

    The ideal gas law is PV = nRT, where n is the number of moles of gas, V is volume, p is pressure, T is temperature and R is the gas constant.

    The form used in the book you quote has instead v = V/n, volume per mole, and reads Pv = RT.

    Thanks. But I still do not know how to interpret the n and n0 in the after equation. Isn't n is 1 mol?
