WebConclusion: I learned how to tell which one was the limiting reactant. In this case, the limiting reactant was K2CO3 because it was lower than the other reactant. The limiting reactant is the one that runs out first and by doing so it limits the amount of product that can form. We had to find the percent yield of CaCO3. Percent yield = (Actual Yield / Theoretical Yield) … Web13 apr. 2024 · I will explain how to solve this, and you can fill in the math. (1) Find the molecular weight of K 2 CO 3 in grams. Either look it up or add the atomic weights: 2K + C + 3O. (2) Divide the given mass of 89.3 grams by the molecular weight of K 2 CO 3. That gives the number of moles of K 2 CO 3. (3) Multiply the number of moles of K 2 CO 3 by ...
