Explanation:
To determine the weight percentage of carbon in the compound, we need to consider the relative atomic masses of carbon and oxygen. Carbon has an atomic mass of approximately 12.01 grams per mole, while oxygen has an atomic mass of approximately 16.00 grams per mole.
Since the compound contains two times as many oxygen atoms as carbon atoms, we can assume a 1:2 ratio. Let's assume we have 1 mole of carbon atoms. This means we would have 2 moles of oxygen atoms.
The total molar mass of the compound can be calculated by adding up the molar masses of the carbon and oxygen atoms. It would be:
(1 mole of carbon * 12.01 g/mol) + (2 moles of oxygen * 16.00 g/mol) = 44.01 g/mol
To calculate the weight percentage of carbon in the compound, we divide the molar mass of carbon by the total molar mass of the compound and multiply by 100:
(12.01 g/mol / 44.01 g/mol) * 100 ≈ 27.28%
Therefore, the weight percentage of carbon in the compound would be approximately 27.28%.
