1. Find the Molar Mass of C2H2O2
* Carbon (C): 12.01 g/mol * 2 = 24.02 g/mol
* Hydrogen (H): 1.01 g/mol * 2 = 2.02 g/mol
* Oxygen (O): 16.00 g/mol * 2 = 32.00 g/mol
* Total Molar Mass: 24.02 + 2.02 + 32.00 = 58.04 g/mol
2. Calculate the Mass Percentage of Oxygen
* Mass of Oxygen / Molar Mass of C2H2O2 * 100%
* (32.00 g/mol) / (58.04 g/mol) * 100% = 55.14%
3. Calculate the Mass of Oxygen in 56 g of C2H2O2
* 56 g * 0.5514 = 30.88 g
Therefore, there are approximately 30.88 grams of oxygen in 56 grams of C2H2O2.
