1. Find the Molar Mass of SO2
* Sulfur (S): 32.06 g/mol
* Oxygen (O): 16.00 g/mol (x2 since there are two oxygen atoms)
* Molar mass of SO2 = 32.06 + (16.00 x 2) = 64.06 g/mol
2. Calculate the Mass Percentage of Each Element
* Sulfur (S):
* (32.06 g/mol S / 64.06 g/mol SO2) x 100% = 50.04%
* Oxygen (O):
* (32.00 g/mol O / 64.06 g/mol SO2) x 100% = 49.96%
Therefore:
* The mass percentage of sulfur (S) in SO2 is approximately 50.04%.
* The mass percentage of oxygen (O) in SO2 is approximately 49.96%.
