Webmass MgBr2 = 180 g. Using 140 g of Br2. mass MgBr2 = 140 g Br2 × (1 mol Br2 / 159.8 g Br2) × (1 mol MgBr2 / 1 mol Br2) × (184.1 g MgBr2 / 1 mol MgBr2) mass MgBr2 = 161 g. Step 3: Determine the limiting reagent. Since Br2 produces less amount of MgBr2 than Mg, Br2 is the limiting reagent. Step 4: Determine the theoretical yield. WebMar 28, 2024 · The most basic way to calculate enthalpy change uses the enthalpy of the products and the reactants. If you know these quantities, use the following formula to work out the overall change: ∆H = Hproducts − Hreactants. The addition of a sodium ion to a chloride ion to form sodium chloride is an example of a reaction you can calculate this way.
