Stoichiometry

The amount of substance containing $6.02 \times 10^{23}$ elementary particles.

The mass of one mole of a substance ($g \cdot mol^{-1}$).

The quantitative relationship between reactants and products in a chemical reaction.

The simplest whole-number ratio of atoms of each element in a compound.

The actual number of atoms of each element present in a molecule.

The maximum amount of product that can be formed from the limiting reactant.

(Actual Yield / Theoretical Yield) x 100%.

The reactant that is completely consumed and determines the maximum product yield.

The reactant that remains after a chemical reaction has stopped.

The volume occupied by one mole of any gas at STP ($22.7 \text{ dm}^3 \cdot mol^{-1}$).

Standard Temperature and Pressure ($273\text{K}, 100\text{kPa}$).

The equation of state relating pressure, volume, temperature, and moles ($PV = nRT$).

The amount of solute dissolved in a unit volume of solution ($mol \cdot dm^{-3}$).

Analytical method used to determine the concentration of a substance by reacting it with a standard solution.

Two-stage titration used when the sample is insoluble or the endpoint is hard to see.
