본문내용

1. purpose

• To derive Avogadro`s number (the number of molecules in a mole of a
substance), using an oil layer on water.
• The point concepts : Avogadro`s number, mole, monolayer
• Related concepts : molar mass, polar molecule, non-polar, molecule

2. Theory

• Avogadro`s number, = 6.022×1023)/ mole
The number of atoms in exactly 12 grams of carbon-12
( : volume of carbon atom 1 mole
: volume of 1 carbon atom)
• mole
A chemical unit for the amount of substance.
The number is set to Avogadro`s number
• Polar molecule and non-polar molecule
Molecules are made up of atoms which do not always share electrons equally.
When the atoms share electrons unequally, an asymmetry in molecular charge
results -> polar molecule
When they share equally symmetry is achieved -> non-polar molecule
