2*mol, 4*mol, and 2*mol of carbon, hydrogen, and oxygen atoms respectively.

Explanation:

And had the question asked how many C,H,O atoms in a "dozen" such molecules, I think you would have been able to answer 24, 48, and 24 atoms respectively.

And the mole is simply a (much) larger number, 6.022xx10^23*mol^-1, where 1 mole of C specifies a mass of 12.01*g. Capisce?
