  1. The following lesson is one lecture in a series of Chemistry Programs developed by Professor Larry Byrd Department of Chemistry Western Kentucky University

  3. Scientific Notation (Part 4) CHECK TEST #1 QUESTIONS

  4. SCIENTIFIC NOTATION CHECK TEST #1QUESTIONS If your instructor requires you to do so, "TYPE" or "PRINT" out each of the following questions and then "show your work“ on 3-holed lined notebook paper. YOU CANNOT DO ANY PART IN YOUR HEAD !!!

  5. 1. Give the following in scientific notation. Also, write each in correctly writtenscientific notation computer form! YOU CANNOT DO ANY PART IN YOUR HEAD !!! • A. 648 = ? • B. 0.00162 = ? • C. 96,000,000 (as two significant figures)

  6. 1. Give the following in scientific notation. Also, write each in correctly writtenscientific notation computer form! YOU CANNOT DO ANY PART IN YOUR HEAD !!! D. 30,000,000,000 x 10-4 (as one significant figure) E. 0.00468 x 10-3 (as three significant figures) F. 94.6 x 10-4 (as three significant figures)

  7. 2. Convert the following into conventional numbers (every-day-way-of-writing numbers).If part of the number is in scientific notation form, then you must get all the given problem into correctly written scientific notation form before converting it back into its conventional number. YOU CANNOT DO ANY PART IN YOUR HEAD !!! A. 7.82 x 10-4 B. 9.34 x 103 C. 0.00381 x 10-2

  8. 3. Use scientific notation to work the following problems: "Do" all work in scientific notation! Give "ALL" answers in scientific notation! IMPORTANT NOTE: If one part of the problem is in a fraction form, then all parts MUST BE converted into fraction forms and then treated as a large fraction. YOU CANNOT DO ANY PART IN YOUR HEAD !!! A. (6.20 x 10-2) (3.00 x 10-1) = ? (answer as 3 significant figures) Make sure every part is in correctly written scientific notation form before you do “ANY” multiplying or dividing. B. (0.514 x 10-3) (4.20 x 103) (answer as 3 significant figures)

  9. 3. Use scientific notation to work the following problems: "Do" all work in scientific notation! Give "ALL" answers in scientific notation! IMPORTANT NOTE: If one part of the problem is in a fraction form, then all parts MUST BE converted into fraction forms and then treated as a large fraction. C. (124,000) (48.1) (12.0) (1.00) (answer as 3 significant figures) D. ( 87.6 ) = ? (answer as 2 significant figures) E. 4.00 x 104 divided by 2.00 x 103 (as 3 significant figures) YOU CANNOT DO ANY PART IN YOUR HEAD !!!

  10. 3. Use scientific notation to work the following problems: "Do" all work in scientific notation! Give "ALL" answers in scientific notation! IMPORTANT NOTE: If one part of the problem is in a fraction form, then all parts MUST BE converted into fraction forms and then treated as a large fraction. YOU CANNOT DO ANY PART IN YOUR HEAD !!! • F. 68.0 x 10-3 (as 3 significant figures) • 4.61 x 10-1 • (6.20 x 10-3) (3.00 x 104) (as 3 significant figures) H. [ ] [16.4 X 10-7] [ ] (as 3 significant figures) 10.6 x 10-4 0.0641 x 10-2 0.111 x 104 10.0 x 102

  11. YOU HAVE COMPLETED JUST PART – IV OF SCIENTIFIC NOTATION
