Specific heat of hydrogen at constant pr...

Specific heat of hydrogen at constant pressure `C_(p) = 29 "joule kelvin"^(-1) mol^(-1)`.
(a) Find dimensions of `C_(p)`.
(b) Unit of length is changed to `50 cm`, unit of time is changed to `2sec`, unit of temperature is changed to `2K`, keeping units of mass and amount of substance same. Find the value of specific heat of hydrogen in new system of units.
