Stoichiometric Calculations (Grade 11 NSC Matric Physical Sciences): Flashcards

Calculating quantities in reactions using balanced equations

Bridge between mass, concentration, volume, and number of moles

$n = \frac{m}{M}$

$C = \frac{n}{V}$

Reagent completely used up; stops reaction when consumed

Reagent not completely used up; remains after reaction

$\frac{\text{actual yield}}{\text{theoretical yield}} \times 100$

Maximum amount of product calculated using stoichiometry

Simplest formula showing ratio of atoms of each element

$\frac{\text{mass of compound}}{\text{mass of sample}} \times 100$
