The Mole
Q1.What is a mole in chemistry?
6.022 × 10²³ particles (Avogadro's number). Like a "dozen" but for atoms and molecules.
Q2.What's molar mass?
The mass of one mole of a substance, in g/mol. Equal to the atomic or molecular mass from the periodic table.
Q3.How many grams is one mole of water (H₂O)?
18 g/mol. Hydrogen is 2×1 = 2, oxygen is 16, total = 18.
