How many molecules are in 4 moles of carbon dioxide? Show your work.

A mol of Carbon Dioxide is equal to the mass of 2 oxygen atoms plus the mass of 1 carbon atom.

Mass of Oxygen atom is 16. 16 x 2 = 32

Mass of Carbon atom is 12.

32 + 12 = 44

So that’s the mass of a mol of CO2. Just multiply that by 4 mols.

44 x 4 = 176 grams
