1/30/2012 Standards: 3My Website - www.MrWiggerSci.com/chem

Objectives:

1. be able to recognize 6.02 x 1023 = mole = Avogadro's Number

2. be able to convert from representative particles<----> moles

DO NOW:

1. Write 1 paragraph (5-10 sentences) on a separate sheet of paper, not on

your whiteboard. (5 pts) MISC (turn in to basket when completed)

REFLECTION Subject: What do you plan to do different this semester

than you did last semester? This should be something(s) that will allow

you to improve your grade and/or perform well on the CST test.

HOMEWORK:

Representative particles can be atoms

or molecules (aka formula units)

Page 310


1 30 2012 standards 3 my website mrwiggersci chem o bjectives

1 mol = 6.02 x 1023

1 mol Na atoms = 6.02 x 1023 Na atoms

1 mol NaCl = 6.02 x 1023 NaCl molecules

1 doz = 12

1 doz eggs = 12 eggs

1 gross = 144

1 gross eggs = 144 eggs

Representative Particles:

molecules - example NaCl

atoms - example Ti or N or Al


1 30 2012 standards 3 my website mrwiggersci chem o bjectives

A mole is just a number: 6.02 x 1023

·If 1 mol Al atoms = 6.02 x 1023 Al atoms, How many atoms are in 3.5 mol of Al ?


1 30 2012 standards 3 my website mrwiggersci chem o bjectives

If you have 4.6 mol B,

how many B atoms?

Show Gifted Hands w Cuba Gooding, Jr. What makes learning fun and enjoyable? How do you make you mark in the world. When you are dead - how many will come to your funeral and why? I'll tell you - those who you have had a positive influence on. How will you be remembered. Pray like there is no tomorrow and live as if you will survive to be 100 yrs old (Ben Franklin)
