Web[Use: NA = 6. 023 × 10 23 Atomic masses in u : C = 12. 0; O = 16. 0; H = 1. 0] Solution 1. Definition of Combustion: Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. 2. The reaction involved in the Combustion of ethane: C 2 H 6 + O 2 → 2 CO 2 + 3 H 2 O 3. Calculation: WebEvery mole of SO2 requires one mole of S and one mole of O2. 6.023 x 10^24 molecules is 10 moles. The atomic mass of S is 32 g/mol and the molecular weight of O2 is also 32 g/mole. So, 10 moles of each will be 320 g. 4 More answers below Barry Austern
