Help?

Answer 1

1 mol of CO2, 1 mol of C and 2 mols of O

Answer 2

well one mole of CO ( like a mole of any compound ) will have 6.023 X 10^23 molecules . Since you have 2.49 X 10^23 molecules  this will be

2.49 X 10^23 molecules / 6.023 X 10^23 molecules /mol  the molecules cancel and the answer IS   0.413 moles
