Mole Conversions and Stoichiometry
Conversions between mass, moles, molecules, and chemical stoichiometry steps.
Mole Conversions and Stoichiometry Steps
Grams to Moles: divide mass by molar mass (g / MM = mol).
Moles to Molecules: multiply moles by Avogadro's number (mol * 6.022x10^23 = molecules).
Molecules to Moles: divide molecules by Avogadro's number (molecules / 6.022x10^23 = mol).
Moles to Grams: multiply moles by molar mass (mol * MM = g).
Stoichiometry Step 1: write and balance the chemical equation based on the word problem.
Stoichiometry Step 2: convert mass of original substance to moles by dividing by its molar mass.
Stoichiometry Step 3: multiply by the mole ratio (target substance coefficient / original substance coefficient).
Stoichiometry Step 4: convert target moles to grams by multiplying by the target substance's molar mass.
