  2. Question 1 Write out the metric conversion line on your whiteboard _____________________________________

  3. Follow up Which side is has the larger units? Smaller units?

  4. Question 2 • What are the base units for the following: • Time • Length • Mass

  5. Follow up Does the metric conversion line work with any base unit? (Yes or No)

  6. Question 3 How many centimeters are in a meter?

  7. Follow up How many milliliters are in a liter?

  8. Question 4 Convert 5.6 x 103 nm to m. SHOW WORK!

  9. Follow up How many nanosecond are there in a second?

  10. Question 5 Fill in the correct word or numbers in the blanks below: 1 mole = ____________ molecules/atoms/particles/formula units 1 mole = ____________ Liters 1 mole = ____________ grams/mole

  11. Follow up Where can you find the first two answers in the previous question?

  12. Question 6 Convert 34.5 L of F2 gas at STP to moles? SHOW WORK!

  13. Follow up Does STP affect the problem at all?
