Answer:
To find the mass percentage of each element in carbon dioxide (CO2), you'll need to consider the molar masses of the individual elements in the compound, which are carbon (C) and oxygen (O). The molar mass of carbon is approximately 12 g/mol, and the molar mass of oxygen is approximately 16 g/mol.
Now, let's calculate the mass percentage of each element in CO2:
1. Carbon (C):
- Molar mass of carbon (C) = 12 g/mol
- In one molecule of CO2, there is 1 carbon atom.
- So, the mass of carbon in 1 mole of CO2 = 1 * 12 g = 12 g
2. Oxygen (O):
- Molar mass of oxygen (O) = 16 g/mol
- In one molecule of CO2, there are 2 oxygen atoms.
- So, the mass of oxygen in 1 mole of CO2 = 2 * 16 g = 32 g
Now, you can calculate the mass percentages:
- Mass percentage of carbon in CO2 = (Mass of carbon / Molar mass of CO2) * 100%
= (12 g / 44 g) * 100% ≈ 27.27%
- Mass percentage of oxygen in CO2 = (Mass of oxygen / Molar mass of CO2) * 100%
= (32 g / 44 g) * 100% ≈ 72.73%
So, the mass percentage of carbon in carbon dioxide is approximately 27.27%, and the mass percentage of oxygen is approximately 72.73%.
