Quantitative Chemistry - Calculating with Moles

Why do we have to be able to convert between moles and grams?

Although elements and chemicals react with each other in molar ratios, in the laboratory we use digital balances and grams to measure quantities of chemicals as it is impractical to try and measure out moles

How do you calculate moles?

Moles = Mass/Molar Mass

How do you calculate mass?

Mass = Moles x Molar Mass

How do you calculate molar mass?

Molar mass = mass / mole

What does one mole contain?

One mole of a substance contains the same number of the stated particles or atoms or ions as a mole of any other substance

ONE MOLE =

6.02 x 1023 of whatever is being described. The number of entities in mole is the Avogadro constant (6.02 x 1023)
