1. Find the Molar Mass of CO2:
* Carbon (C) has a molar mass of 12.01 g/mol
* Oxygen (O) has a molar mass of 16.00 g/mol
* CO2 has one carbon and two oxygen atoms, so its molar mass is: 12.01 g/mol + (2 * 16.00 g/mol) = 44.01 g/mol
2. Use the Formula:
* Moles = Mass / Molar Mass
3. Calculate:
* Moles = 28 g / 44.01 g/mol
* Moles ≈ 0.64 mol
Therefore, there are approximately 0.64 moles in 28 grams of CO2.
