Theoretical value of g
Webb7 juli 2024 · MgCO 3 → MgO + CO 2. The calculation is simple if you know the actual and theoretical yields. All you need to do is plug the values into the formula: percent yield = actual yield / theoretical yield x 100%. percent yield = 15 g / 19 g x 100%. percent yield = 79%. Usually, you have to calculate the theoretical yield based on the balanced equation.
