KAUFFMAN
11 - 12 January 2011
10 – 11 College
Prep Chemistry B
DO NOW:
Find your new seats using the posted seating chart, download necessary files.
Use a Venn Diagram to compare and contrast unit conversions and the conversions between mass, moles,
number of particles, and/or volume of a gas at STP.
California
Standards:
Standard 3d: Use molar mass to determine grams, moles, number of particles, and volume of a gas at STP.
Standard IE1a: Select and use appropriate tools (mathematics tools, in this case).
Essential
Questions:
If we are given the mass of an element in units other than grams, how do we find the number of moles?
LEARNING OBJECTIVES FOR STUDENTS:
Worksheets on unit conversions, scientific notation, and metric prefixes; compass learning
Given:
the learner
will:
solve chemistry problems involving the conversion between mass, moles, number of particles, and/or the
volume of a gas at STP
by:
applying unit conversions and scientific notation using the dimensional factor analysis method.
Assessment: Practice problems, unit worksheets, and compass learning assessments.
Individual Instruction:
Collaborative Station:
•
Read and take Cornell Notes on the
handout packet on pages (in this
order) 7, 6, and 8.
•
Solve problems 1 – 5 on each
problem set (there are four sets to
complete) and compare your
answers to the key posted. Show all
of your work using the dimensional
analysis factor method on page 6
for each problem on pages 6 and 7.
•
Take the Compass Learning quiz on
unit conversions.
•
Complete the rest of the problems
on pages 6 – 8.
•
Exit slip will be your progress on the
worksheets.
Assignment for Monday:
•
Read and take Cornell Notes on
Significant Figures (pages 9 – 11)
and solve questions 1 – 5 on each
section, showing your work.
Direct Instruction:
•
Metric prefixes, dimensional analysis
factor method, and scientific
notation problems involving
chemical quantities.
• Complete the two problem sets on the
exit slip for collaborative station.
• Using the notes provided in direct
instruction, practice writing Jeopardy
style questions for the Cornell Notes
provided. Compare your questions
with your elbow partner.
• If you finish with this, work on your
personal science dictionary.
Collaborative Station Exit Slip: On a piece of paper, each student
should solve these two problems with their elbow partner. Use the dimensional factor
analysis method (page 6 of worksheet packet).
1. You have 1,369 mg of a compound, which has a molar mass of 167.3 g/mol.
a.
b.
c.
d.
How many grams of the compound do you have?
How many moles of the compound do you have?
If the compound is a gas at STP, what volume would it occupy in L?
What volume would it occupy in mL?
2. You have 9.876x1018 molecules (particles) of a compound, with a molar mass of
542.2 g/mol.
a.
b.
c.
d.
How many moles of this compound do you have?
How many mmol of this compound do you have?
Using your answer from (a), how many grams of this compound would you have?
How many mg of the compound would you have?
Recall: NA = 6.022x1024 particles/mole & an ideal gas occupies 22.4 L/mol at STP.
