What is a mole?
A mole is a unit representing 6.022 x 10²³ particles (atoms, molecules, ions, etc.).
What is molar mass?
The mass in grams of one mole of a substance, expressed in g/mol.
What is Avogadro's number?
The number of particles in one mole of a substance: 6.022 x 10²³.
What is dimensional analysis?
A technique for converting between different units using conversion factors to cancel out unwanted units.
Define atomic mass.
The mass of one atom in atomic mass units (amu); numerically equal to molar mass in g/mol.
What are the key differences between atomic mass and molar mass?
Atomic Mass: Mass of a single atom in amu | Molar Mass: Mass of one mole of a substance in g/mol. Numerically the same, but different units and scales.
What are the differences between moles and grams?
Moles: A unit of amount (6.022 x 10²³ particles) | Grams: A unit of mass. Moles are converted to grams using molar mass.
