  1. Converting Grams To Moles and Moles To Grams By Rochelle Berk and Shelly Huff

  2. Atomic Mass (Single Element) • The atomic mass of a single element can be found on the periodic table of elements • The atomic mass of an element can be found usually in the upper right hand corner of that element’s box. Example: Potassium’s atomic mass is 39.10g/mol Aluminum’s atomic mass is 26.98g/mol

  3. Oxygen (O) Sodium (Na) = 16 grams/mole = 22.9 grams/ mole Examples of Atomic Mass (Single)

  4. Atomic Mass (Combined Elements) • The atomic mass of combined elements can be found by adding together the atomic mass’s of all the elements. • Example: H2O = 18 g/mol NaCl = 58.44 g/mol

  5. H2O (H2= 1+1; O= 16: 1+1+16) NaCl (Na= 23; Cl= 35.5: 23+35.5) = 18 grams/mole = 58.5 grams/mole Examples of Atomic Mass (Combined)

  6. How You Convert • When converting from grams to moles, first take the given number of grams of that element(s) • Next, multiple it by [1 mole of your element divided by the atomic mass of your element (grams)] • You now have converted grams to moles

  7. Examples of Converting Grams to Moles • 100 g Al *1 m Al 26.9 g Al = 3.72 m Al • 200 g H2O *1 m H2O 18.0 g H2O = 11.0 m H2O

  8. How You Convert • When converting moles to grams, you take the given number of moles of the element(s) • Next, you multiply that number by [the atomic mass of the element(s) divided by one mole of the element] • You have now converted moles to grams!

  9. Examples of Converting Moles to Grams • .0500 m Cu *63.5 g Cu 1 m Cu = 3.00 g Cu • .090 m NaCl *58 g NaCl 1 m NaCl = 5.0 g NaCl

  10. Quiz Time! • How many moles are in 26 grams of N2O? • If there are .5400 moles of FeSO4, how many grams are there? Answer! Answer!

  11. Answers! 1.) 0.590 moles Of N2O Back to Quiz 2.) 82.08 grams of FeSO4 Back to Quiz

  12. Good Job! • Now that you know how to convert both moles to grams and grams to moles, go have fun and learn, learn, learn!
