Chemical Equations: Moles and Mass Calculations (HSC SSCE Chemistry): Flashcards

Mole ratios of reactants and products

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

$m = n \times MM$

Number of moles

Molar mass (mass of one mole in g/mol)

Mass of reactants = mass of products

Mass → Moles → Moles → Mass

To obtain correct stoichiometric mole ratios

Exact ratio substances react and form in

Mass in grams
