How do you find the J/mol/degrees celsius number (sorry I forgot the name of it)? In this question that number was different for constant volume and fro constant pressure but how is it found? Thanks

R=8.314 J x C^-1 x mol^-1 is the gas constant.
(a) The molar heat capacity of a monatomic ideal gas at constant pressure is Cp,m = 5R/2 = (20.8 J x C^-1 x mol ^-1).
(b) The molar heat capacity of a monatomic ideal gas at constant volume is Cv, m = 3R/2 = (12.5 J x C^-1 x mol ^-1).

Can you please explain how you know those values? Are they listed somewhere in the textbook?
