How to find moles and molecules/atoms for C12H22O11and FE and H20
Molar Mass Lab Introduction: The mole represents a number. It is the number 6.022 x 1023. A mole of hydrogen atoms contains 6.022 x 1023 hydrogen atoms. A mole of water contains 6.022 x 1023 molecules of water. A mole of carbon dioxide contains 6.022 x 1023 molecules of carbon dioxide. Objective: To determine which of the samples on your table contains the most atoms. Procedure: Determine the mass of each element on your table. Be gentle when placing objects on the balance. Record your data on the table Station 1- Table Sugar Measure a teaspoon of table sugar. 2. Calculate the molar mass of table sugar (a.k.a. sucrose - C12H22O11) 3. Now, weigh the table sugar in your scoop. Record the weight. 4. Calculate the moles of table sugar in the teaspoon. 5. Calculate the amount of molecules in the teaspoon of table sugar. (Hint: Use your answer from #4 as your starting point!) 1. Station 2- Nails/Screws 6. Find a nail or a screw. 7. Calculate the molar mass of Fe. 8. Now, weigh the nail/screw. Record the weight. 9. Calculate the moles of Fe in the nail/screw. 10. Calculate the amount of molecules in Fe. (Hint: Use your answer from #9 as your starting point!) Station 3- Water 11. Measure a % cup of water. 12. Calculate the molar mass of water. 13. Now, weigh the water. Record the weight. 14. Calculate the moles of water in a % cup. 15. Calculate the amount of molecules in the 4 cup of water. (Hint: your starting point!) your answer from #14 as
