Mole Concept : Mole to Volume, Volume to Mole, Mole to Representative Particles, Representative Particles to Mole, & Percentage

MOLE CONCEPTS

* remember that 1 mole of any gas will always have a volume of 22.4 Liters when the gas is at standard temperature & pressure.

MOLE TO VOLUME

    

Example:

atoms = 1 mol:

VOLUME TO MOLE

V= n x v

Example: 

atoms = 1 mol:

MOLE TO REPRESENTATIVE PARTICLES

(desired moles)(6.02x10^₂₃part/1 mol)=answer

Example: 

How many grams of oxygen gas are in 4.5 moles of oxygen gas?

6.02*10²³ times 4.5

answer: 2.709*10²⁴

^{REPRESENTATIVE PARTICLES TO MOLE
(desired moles)=(6.02x10₂₃part/1 mol)}
