Stoichiometry Overview • Recall that in stoichiometry the mole ratio provides a necessary conversion

Stoichiometry Overview • Recall that in stoichiometry the mole ratio provides a necessary conversion factor: molar mass of x molar mass of y grams (x) moles (y) grams (y) mole ratio from balanced equation • For solutions: mol/L of x mol/L of y volume (x) moles (y) volume (y) mole ratio from balanced equation

What types of information can we solve for? • A concentration of any chemical

What types of information can we solve for? • A concentration of any chemical in mol/L • The volume of a chemical required to react with another • Mass of a chemical • Moles of a chemical
