Name ___________________________________________ Date ________________ Period __________ Part II: Moley-moley-moley One mole is _____________________________ things. That’s 602 hexillion! This is also called Avagadro’s number. Three examples of a mole:

Example: Water Nitrogen Ammonia Gold Uranium Sodium hydroxide Mass of one mole Molarity Example: A one molar solution of NaCl has one mole of NaCl for every one liter of water. How many grams of NaCl does it take to make 1 L of a 1 M solution? How many grams of NaOH are needed to make 3 L of a 1.5 M solution?

What is the molarity of 5 L of solution with 50 g of KOH dissolved in it? STP = Which is _____ °C and ______ atm. 1 mole of an ideal gas at STP is equal to ___________ L How many moles of an ideal gas are there are in 60 L? How many moles of an ideal gas would it take to fill 100 pop bottles? How much space would 700 moles of an ideal gas take up?

Reactions! H 2 + O 2  H 2 O222 The _______________ equal the number of ___________ required! Fe + Cl 2  FeCl 3 Zn + HCl  ZnCl 2 + H 2 Cu + AgNO 3  Cu(NO 3 ) 2 + Ag So how many grams of copper and silver nitrate would you need to complete this reaction? How many grams silver do you get out?
