Mole Problems

Today in chemistry we went over homework pages which was pages 1 & 2.


Then we worked on page 3 and completed the first 2 problems by converting atomic masses to calculate how many moles were present. Problems c,d and e were to be completed for homework along with page 4.Then we started the lab, 'Mole Stations Lab' where we went from station to station to convert masses to moles and moles to masses. Some converstions to remember are:
1 mole= 6.02 x 1023 atoms or molecules.

To find the molecular mass you add the masses of all the compounds. That can be used later to find the number of moles of an element.
