Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Stoichiometry

Stoichiometry is the calculation of reactants and products in chemical reactions based on the balanced chemical equation. It involves using mole ratios derived from the coefficients of the balanced equation to determine how much of each substance is consumed or produced. Understanding stoichiometry is essential for determining theoretical yields and comparing them to actual yields in a reaction.

Percent Yield

Percent yield is a measure of the efficiency of a chemical reaction, calculated by comparing the actual yield of a product to the theoretical yield. It is expressed as a percentage and is calculated using the formula: (actual yield / theoretical yield) × 100%. This concept is crucial for evaluating how well a reaction proceeds and identifying any losses that may occur during the process.

Molar Mass

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a molecule. Knowing the molar masses of reactants and products is vital for converting between grams and moles, which is necessary for stoichiometric calculations and determining theoretical yields in chemical reactions.
