Learning outcomes

Students will be able to:

• Explain the mole as a counting unit equal to 6.022 × 10²³ particles, and why one mole of different substances has different masses.
• Calculate the molar mass of a compound from its formula and the periodic table.
• Convert between grams, moles, and number of particles, using moles as the central step.
• Use mole ratios from a balanced equation to predict amounts of reactants and products.

Standards alignment

• HS-PS1-7 NGSS: Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction (mole and mass relationships).
• HSN-Q.A.1 CCSS Math: Use units to understand problems and to guide the solution of multi-step problems.
• SEP 5 NGSS Science and Engineering Practice: use mathematics and computational thinking.

Includes

Four stages: weighing out one mole of six substances, molar mass for nine formulas, a clickable mole road map for six conversion types with fresh numbers each time, and six mole-ratio problems from balanced equations; and a printable lab worksheet. A teacher answer key is available from Logical Home Schooling.
