Answer 2

Comparing the Molar Mass of SO2 and SO3

The molar mass of a substance is the mass of one mole of that substance. In the case of molecules like SO2 and SO3, the molar mass can be calculated by adding up the atomic masses of the atoms in the molecule.

Molar Mass of SO2: The molar mass of SO2 (sulfur dioxide) can be calculated by adding the atomic masses of sulfur and oxygen in the molecule. Sulfur has an atomic mass of approximately 32.07 g/mol, and each oxygen atom has an atomic mass of approximately 16.00 g/mol. Therefore, the molar mass of SO2 is approximately 32.07 + 2 * 16.00 = 64.07 g/mol.

Molar Mass of SO3: Similarly, the molar mass of SO3 (sulfur trioxide) can be calculated by adding the atomic masses of sulfur and oxygen in the molecule. Sulfur has an atomic mass of approximately 32.07 g/mol, and each oxygen atom has an atomic mass of approximately 16.00 g/mol. Therefore, the molar mass of SO3 is approximately 32.07 + 3 * 16.00 = 80.07 g/mol.

Comparison: So, the molar mass of SO2 is approximately 64.07 g/mol, while the molar mass of SO3 is approximately 80.07 g/mol.

Conclusion: Therefore, the molar mass of SO3 is higher than the molar mass of SO2 by approximately 16 g/mol.
