+ How is the magic done?

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

+ 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

+ 1)Write the main number and move the decimal as many places as indicated 2.03x x10 23

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

+ 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

+ 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 x 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 molecules
