learn.whatIsHeading

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.

分步指南

1. 1Write and balance the chemical equation
2. 2Convert given mass to moles (mass / molar mass)
3. 3Use mole ratio from equation to find moles of target
4. 4Convert moles back to mass (moles × molar mass)
