(Coefficients equal to one (1) do not need to be shown in your answers). 2 Fe+ 3 Cl2 −−→ 2 FeCl3. 4 Fe+ 3 O2 −−→ 2 Fe2O3. 2 FeBr + 3 3 H2SO4 −−→ 1 Fe2(SO4) + 3. (d) 1 C4H6O3 + 1 H2O −−→ 2 C2H4O2.

  2. The formula to calculate equivalent weight is: Equivalent weight = Atomic weight / Valence For example, the equivalent weight of sulfuric acid (H2SO4) is calculated as follows: Equivalent weight = Molecular weight / Acidic hydrogen ions Equivalent weight of H2SO4 = 98 / 2 = 49 So, the equivalent weight of sulfuric acid is 49 g/equivalent.
