Composition of Substances and Solutions (Chemistry)

Recall cards on the composition of substances and solutions: formula mass and the mole concept (formula versus molecular mass; the mole and Avogadro's number; molar mass and mass-mole-entity conversions); determining empirical and molecular formulas (percent composition; deriving an empirical formula from element masses or percent composition; the whole-number multiple linking empirical and molecular formulas); molarity (solution, solvent, solute, and aqueous solution; concentration; molarity and its unit; dilution and the dilution equation); and other units for solution concentrations (mass percentage, volume percentage, mass-volume percent, parts per million, and parts per billion).
