find the molecular composition of oxygen in sulfur dioxide
Explanation:
Sulfur dioxide has sulfur (S) and oxygen (O) present. ... The molar mass of sulfur is 32.1 g/mol, and oxygen is 16.0 g/mol. If you look back at the formula ( SO2 ), you can see that there is one sulfur and two oxygens present. Therefore, the molar mass of sulfur dioxide is [1 × 32.1 + 2 × 16.0] = 64.1 g/mol.
