Final answer:
To calculate the percent yield, we need the actual yield and the theoretical yield. However, in this scenario, we lack sufficient information to determine the theoretical yield of the CaCO3 from the given reactants. We need more details on the reaction to complete the calculation.
Step-by-step explanation:
The student is calculating the percent yield of a chemical reaction, which is a common task in chemistry. To find the percent yield, we use the formula: percent yield = (actual yield / theoretical yield) × 100%. In this case, the actual yield is the mass of CaCO3 produced, which is 0.510 g.
To determine the theoretical yield, we'd need to calculate the amount of product that could be formed from the limiting reactant, which can be done using stoichiometry. However, since the theoretical yield is not provided, we cannot calculate the percent yield. Typically, the theoretical yield is calculated based on the balanced chemical equation and the amount of the limiting reactant.
If we assume that 1.00 g of CaCl2 reacts completely and is the limiting reactant, we could calculate the theoretical yield from that amount; however, without further information about the reaction conditions or the remaining reactants, a precise calculation cannot be made here.
