Help in AS Chemistry!

The question is: What is the minimum mass of CO in highly polluted air you would expect to collect over 24 hours if the 8 hour running average is 20 ppm (parts per million)?

The formula: concentration (ppm) = mass of component (CO)/mass of solution (air) x 1,000,000 

They did not tell me the mass of air and so I though maybe I could use the following formula...

mass = amount(number of moles) x molar mass

but now I don't know the amount and so am terribly confused!

Any help would be appreciated!
