14. If you have 10 Cheeriums, how many Ch2Fp molecules can you make? [Show your work.] Name_________________ Part 1: How big is a dozen? 15. If you have 90 grams of Cheerium, how many Cheerios do you have? [Show your work.] 1. Obtain a cup of Fruit Loops and a cup of Cheerios. The Fruit Loops represent the element Fruitloopogen (Fp) and the Cheerios are Cheerium (Ch). They make a compound “Cheerium Fruitloopide” Ch2Fp # Fruit Loops Cheerios Ch2Fp Mass of 1 (grams) 16. If you have 90 grams of Cheerium, how many Ch2Fp molecules can you make? Mass of 12 (grams) [Show your work.] 17. If you have 48 Ch2Fp molecules, how many dozens do you have? 18. What is the mass of 48 Ch2Fp molecules? 2. What is the “dozen mass” of Ch2Fp ? ______________ 3. Write a chemical equation for the synthesis of Ch2Fp . (Ch is diatomic, Fp is not.) 4. How many Ch2Fp molecules can you make from the cereal in your cups? 5. How many dozens of Ch2Fp molecules can you make from the cereal in your cups? 6. If you have 4 dozen Ch2Fp molecules, what will the mass be?_________ 7. How many dozens are in 26,500 grams of Ch2Fp ? ____________ 8. What is the mass of 1,000 Ch2Fp? _____________________ 9. What is the ratio of Cheerium to FruitLoopogen. 10. What is the mass ratio of Cheerium to FruitLoopogen. 11. If you have 10 hydrogen atoms, how many water molecules can you make? 10 hydrogen atoms X 1 Oxygen atom = 5 water molecules 2 Hydrogen atoms 19. How many grams of Cheerium are in 48 Ch2Fp molecules?

Part 1: How big is a mole? Using your cereal models, you are going count how many Ch2Fp molecules you can make in a minute. You may use your cell phones or borrow a timer. Ch2Fp molecule synthesis rate = ______________ molecules/minute Show your work on the following. Include units and write it out in dimensional analysis format. Example for 8 molecules per minute. 60 minutes X 8 molecules = 480 molecules 1 minute 1. How many could you make in an hour at that rate? 2. How many could you make in a year at that rate? 3. Calculate the mass of Ch2Fp molecules you could make in a year. 4. How long would it take you to make a million Ch2Fp molecules? 5. How long would it take you to make a mole of Ch2Fp molecules? 6. What is the mass of one mole of Ch2Fp molecules? Extra Credit. How many moles of Ch2Fp molecules would be equal to the mass of the earth. Hint, there are 1,000 grams in a Kilogram. The earth has a mass of 5.97 x 1024 kg. Part 1: How big is a mole? Using your cereal models, you are going count how many Ch2Fp molecules you can make in a minute.
