Homework Statement

how can I calculate specific heat at constant pressure from mass specific heat and mole mass?

I assume that this is a gas and the mass specific heat is at constant volume.

If so, use mass specific heat (heat energy/unit mass) and mass/mole to determine mole specific heat at constant volume (Joules /(mol. K)).

What is the relationship between Cp and Cv for a gas? (Hint: what is Cp-Cv?)

thanks for answer:) this is perfect gas and the specific heat is not volume, but this which is ptex]4200\frac{J}{kg\cdotK}[/tex] for water - how can I calculate this from this?
