Uncertainty in measurementIf you want to learn more check out What is the overview structure of the protein?

Uncertain = an estimated digit

A measurement always has some degree of uncertaintyDon't forget about the age old question of What is meant by rule of 72?

Exact numbers

Exact number = obtained

  • Counting objects = objects are counted
  • Example: 4 pizzas, 2 balls
  • Defined relationships: from numbers in a defined relationship
  • Example: 1 ft = 12 in
  • 1m = 100cm

We also discuss several other topics like What is an acute injury?

Chapter : 2

Lecture 3: significant figures, conversion factors, density

Significant figures

  • Include both the certain and the estimate measurement

Eules:

  1. All nonzero digits - significant
  • 21.2         3 significant figures
  1. An exact number has infinite numbers of significant figures
  • Counted numbers: 35 pennies
  • Defined numbers: 12 in in 1 foot
  1. Zero is significant when it’s
  • Between nonzero digits
  • 403         3 significant figures
  • At the end of a number with a decimal point
  • 0.050        2 significant figures        500 = 1 significant figures
  • 22.0        3 significant figures        500. = 3 significant figures
  • 20.0         3 significant figures        3.040 x 106 = 4 significant figures
  1. Zero is not significant when its
  • Before the first nonzero digits
  • 0.0043 2 significant figures
  • A trailing zero without a decimal point
  • 2400         2 significant figures
  • 9010        3 significant figures

  • Why 0.056 m only has 2 significant figures?
  • Leading zeroes are not significant
  • Sheet of paper = 5.6 cm         length in meters = 0.056 m (100 cm / m)
  • Use significant figures rules to make sure the answer is as precise as the original measurement

Don't forget about the age old question of machuca soup

Rounding numbers

  • Calculations: often have excess digits that are not significant
  1. Round down
  • When the 1rst digit after what you want is 4 or less
  • 4.639899 round to 2 significant figures
  • 4.7
  1. Round up
  • When the 1rst digit after what you want is 5 or more
  • 0.055893 rounded to 3 significant figures
  • 0.0559

Your turn!If you want to learn more check out What are the different stages of sleep?

        Round 240,391 to 4 significant figures → 240,400

Significant figures in calculations

  • The result of the calculation can not be more precise than the least precise measurement
  • Example: calculate the area of a floor thats 12.5 feet by 10 feet

We also discuss several other topics like What is a boxplot used for?

Base x height

12.5 feet x 10 feet = 125 feet2

But 10. Feet only has 2 significant figures

So answer needs 2 significant figures

125 feet2 → 130 feet2

Calculation with multiplication or division

  • The result has as many significant figures as the measurement with the fewest significant figures
  • 9.00 m x 100 m = 900 m2        (100 only has 1 significant figures)
  • 9.00 , x 100. M = 900. M2        (both has 3 significant figures)
  • 9.0 m x 100. M = 9.0 x 102m2 (9.2 has 2 significant figures)

Calculations with addition and subtraction

  • Result has the same precision (same number of decimal places) as the least precise measurement ( the number with the fewest decimal places)
  • The result must be rounded to the same number of decimal places as the value with the fewest decimal places

Example:

Key idea: match precision rather than significant figures!

Your turn!!

  • Mass of weigh paper = 0.101 g
  • Added CaCL2 to weigh paper until the balance read 1.626 g
  • How much CaCL2 did he weigh out?

1.626 g

-  .101 g

1.525 g
