Question

If 2.47 moles of calcium chloride reacts with fluorine gas, how many grams of calcium fluoride are made?

Answer 1

First, write the correctly balanced equation:

CaCl₂ + F₂(g) ==> CaF2 + Cl₂

Next, use dimensional analysis and stoichiometry to answer the question:

2.47 moles CaCl₂ x 1 mol CaF₂ / mol CaCl₂ x 78.1 g CaF₂ / mol = 193 g CaF₂ are made
