Answer 1

For COMPLETE combustion, you have C(s) + O₂(g) ==> CO₂(g)

mass of C = 2 kg = 2000 g

moles C = 2000 g x 1 mol/12 g = 166.7 moles C

moles O₂ needed = 166.7 moles O₂ since mole ratio is 1 mole C : 1 mole O₂(g)

166.7 moles O₂ x 32 g/mole = 5333 g O₂ needed

If you assume air is about 21% O₂, then you would need 25,397 g air = 25 kg air
