A chemistry student is given a chemical equation for the reaction between calcium chloride and sodium carbonate. The equation is unbalanced and the student must balance it, while ensuring that the correct stoichiometric coefficients for each compound are used. The student must then calculate the mass of product formed when 5.0 grams of calcium chloride react completely with excess sodium carbonate. What is the mass of the product formed?
