The Mole Concept

The Mole Concept

The Mole Concept. Avogadro’s Number. Avogadro’s Number (symbol N ) is the number of atoms in 12.01 grams of carbon. Its numerical value is 6.02 × 10 23. Therefore, a 12.01 g sample of carbon contains 6.02 × 10 23 carbon atoms. The Mole.

Counting Atoms

Counting Atoms

Counting Atoms. Chemistry is a quantitative science - we need a "counting unit." The MOLE 1 mole is the amount of substance that contains as many particles (atoms or molecules) as there are in 12.0 g of C-12. AvogadroPaper. The Mole is Developed. Avogadro’s number.

How Big is a Mole?

How Big is a Mole?

How Big is a Mole?. One mole of marbles would cover the entire Earth (oceans included) for a depth of two miles. One mole of $1 bills stacked one on top of another would reach from the Sun to Pluto and back 7.5 million times. It would take light 9500 years to travel from the bottom

Stoichiometry

Stoichiometry

Stoichiometry. The quantitative study of reactants and products in a chemical reaction. • Whether the units given for reactants or products are moles , grams , liters (for gases), or some other units, we use moles to calculate the amount of product formed in a reaction.
