To calculate the number of moles of carbon dioxide (CO2) in 27 billion tons, you need to follow these steps:
1. Convert tons to grams:
1 ton = 1,000,000 grams
So, 27 billion tons is equal to 27,000,000,000,000 grams.
2. Calculate the molar mass of carbon dioxide (CO2):
- Molar mass of C (carbon) = 12.01 g/mol
- Molar mass of O (oxygen) = 16.00 g/mol
- Molar mass of CO2 = (1 * molar mass of C) + (2 * molar mass of O)
- Molar mass of CO2 = (1 * 12.01 g/mol) + (2 * 16.00 g/mol) = 44.01 g/mol
3. Calculate the number of moles of CO2:
- Moles = Mass (grams) / Molar mass (g/mol)
- Moles of CO2 = 27,000,000,000,000 g / 44.01 g/mol ≈ 613,085,853,577,630 moles
So, 27 billion tons of CO2 represents approximately 613,085,853,577,630 moles of carbon dioxide.
