ATAMSBLAST DIGITAL AGENDA 10 – 11 College Prep Chemistry B KAUFFMAN January 2011 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: Given: Worksheets on unit conversions, scientific notation, and metric prefixes; compass learning 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: 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. Collaborative Station: 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 g/mol. a.How many grams of the compound do you have? b.How many moles of the compound do you have? c.If the compound is a gas at STP, what volume would it occupy in L? d.What volume would it occupy in mL? 2.You have 9.876x10 18 molecules (particles) of a compound, with a molar mass of g/mol. a.How many moles of this compound do you have? b.How many  mol of this compound do you have? c.Using your answer from (a), how many grams of this compound would you have? d.How many mg of the compound would you have? Recall: N A = 6.022x1024 particles/mole & an ideal gas occupies 22.4 L/mol at STP.
