chem- ideal gas equation help?

the question is:
calculate the mass of a sample of carbon dioxide which occupies 20dm3 at 27' C ad 100 kPa.
I just want a method to work it out- a detailed one

You have P, V and T, and R is just a constant. So you can work out n from:

PV = nRT

n is the number of moles - how can you find out the mass of a sample from its number of moles?
