WebWe have six hydrogen atoms in the reactants, so we need six hydrogen atoms in the products. We can get this by having three water molecules: C2H6 + O2 → 2CO2 + 3H2O Now we have seven oxygen atoms in the products (four from the CO 2 and three from the H 2 O). That means we need seven oxygen atoms in the reactants. WebNo. of oxygen (O) atoms in 1 molecule of O2 = 2 No. of oxygen (O) atoms in 1 mol of O2 = 2 x Avogadro number = 2 x 6.022x10^23 = 1.204x10^24 No. of oxygen atoms in 0.625 mol of O2 = 1.204x10^24 x 0.625 = 7.525x10^23 (answer) More answers below Stuart Herring
