Stoichiometry uses balanced chemical equations to calculate the quantities (in mass or moles) of reactants and products in chemical reactions. It is the quantitative foundation of all practical chemistry.
Guida passo passo
- 1Write and balance the chemical equation
- 2Convert given mass to moles (mass / molar mass)
- 3Use mole ratio from equation to find moles of target
- 4Convert moles back to mass (moles × molar mass)
Esempi risolti
Ingresso
CaCO₃ → CaO + CO₂ · 100g CaCO₃
Risultato
56g CaO produced
100/100=1 mol CaCO₃ → 1 mol CaO = 56g
