6. + 1.Scientific Notation allows you to represent _________ and __________ numbers in an easy to read format. Scientific Notation

7. + 1)Find the decimal (create one if there isn’t one) 2)#1: Move the decimal until it reaches a number between 1 and 10. Note: We will round after two digits past the decimal. 1)#2: The number of times you shifted the decimal Note: This number is positive for big numbers and negative for small numbers 8 256 000 000 000.000 000 000 456

8. + 1)Write the main number and move the decimal as many places as indicated 2.03x10 -5 6.02x10 23

9. + 2.Conversion Ratio: _________ mole represents 6.02 x 10 23 atoms or molecules Applied Conversion Table Conversion Ratios 1 ft = 12 in 4 quarts = 1 gallon 4 quarters = 1 dollar

10. + 1)Create a conversion table. 2)Place the given value in the top corner. 3)Use the mole/molecule conversion ratio to convert the given value If you have 3 moles of CO 2, then how many molecules do you have? Conversion Ratios 1 ft = 12 in 4 quarts = 1 gallon 4 quarters = 1 dollar 1mole = 6.02 X 10 23

11. + 1)Create a conversion table. 2)Place the given value in the top corner. 3)Use the mole/molecule conversion ratio to convert the given value If you have 1.204 x 10 24 molecules of Hg, then how many moles do you have? Conversion Ratios 1 ft = 12 in 4 quarts = 1 gallon 4 quarters = 1 dollar 1mole = 6.02 X 10 23 molecules
