Aim: How to convert from particles to moles and vice versa Do Now: In pairs compare and discuss your responses to the homework.

The Mole Mole (mol) = the SI base unit used to measure the amount of a substance 1 mole of anything contains 6.02 x 1023 representative particles

What is Avogadro’s Number 6.02 X 1023 representative particles/mol 1 mol of any substance has 6.02 X 1023 representative particles

What are representative particles? Representative particles refers to the species present in a substance: usually atoms, molecules, or formula units

Solve How many moles of magnesium is 1.25 X 1023 atoms of magnesium? (1.25 x 10^23 atoms of magnesium) x ( 1 mole of magnesium/ 6.02 x 10^23 atoms of magnesium) = 0.208 mol of magnesium

Solve How many atoms can be found in 3.91 moles of xenon?
