The mole and molar solution
• The Mole is the SI Unit for measuring the amount of a substance
• One mole contains the same number of particles as there are in 12g of Carbon-12 (6.022 x 1023 atoms - 6.022 x 1023 is the Avogadro number)
• A molar solution contains 1 mole in 1L of solution

Bonding and how molecules are formed

Types of bonding

Polymerisation

Polymerisation produces macromolecules
• When we build these biological molecules we release water. This is known as a ‘condensation’ reaction

Polymerisation
• When we break these biological molecules down we use water. This is known as a ‘hydrolysis’ reaction
