The Mole Bridge molar mass MASSMOLESPARTICLES ÷ M × Nₐ each dot = 0.033 mol (picture only) mass moles particles
1. Two Formulas n = m / MN = n × Nₐ n = moles · m = mass (g) · M = molar mass · N = particles
2. Avogadro's Number Nₐ = 6.02 × 10²³ 1 mole = 6.02 × 10²³ particles, just like 1 dozen = 12
3. Remember Molar mass = formula mass in grams1 mol H₂O = 18 g = 6.02 × 10²³ molecules
