How do you calculate the mass of carbon atoms in CO2?
You use the relative atomic mass of the atoms.Carbon has a relative atomic atomic mass of 12. Oxygen has a relative atomic mass of 16, so two of them is 32.Hence in whichever mass CO₂ you choose, there will be (12 ÷ (12 + 32)) × 100% = 27.3% to 3sf.
