Mole Ratios and Reaction StoichiometryPage of
12 grams of Carbon-12 and is (6.02x10^23) of a substance Why are moles used instead of mass? Each element/compound has a different mass What is used to give us mole to mole ratios? Coefficients Mass to Moles 1 mol/molar mass
Calculating mole ratios Remember, stoichiometry is the study of mass relations. To master it, you need to be comfortable with unit conversions and balancing equations. From there, the focus is on mole relationships between reactants and products in a chemical reaction. Mass-Mass Stoichiometry Probl...

Using mole ratios from a balanced equation and the molar mass of the substances involved, these calculations can be performed when given the number of moles of a substance, or the grams of a substance. How do you find mass using molar mass? If the moles of a substance are known, the ...

Chapter 3 Stoichiometry 3-1Chapter As you have learned in previous chapters, much of chemistry involves using macroscopic measurements to deduce what happens between atoms and molecules. We will now explore the chemical counting unit that links the atomic and macroscopic scales, the mole. The mole...
