Factorlabel method Also known as dimensional analysis Is

Factor-label method Also known as dimensional analysis. (Is one of my favorite things in math or science) You’d be surprised how few memes there about factor-label method so uh…here.

Why it’s important �It allows you to keep conversions organized and easily understood. �There are two main rules to solving science problems with the factorlabel method: � 1. Always carry along your units with any measurement you use. � 2. You need to form the appropriate labeled ratios (equalities).

Basic Units/Metric System �Grams �Liters �Meters �Celsius �Kelvin

Units �In science, units mean everything. �Without units, you aren’t telling anyone anything. (if you fail to put them in your answers, it’ll be marked wrong 100% of the time) �Major prefixes – K, H, Da, B, d, c, m �Secondary prefixes – micro (µ), Nano (n), Pico (p)

Derived Units �More ◦ ◦ ◦ than one measurement Density Speed Newton Acceleration Anything which you can describe as a “something per something, rates”

How factor label is used �How many centimeters in 2 meters?

H 0 w 1 t’ 5 u 53 d: Basic Metric � 1. 6 � 36 m into mm g into kg � 470 � 18 m. L into k. L mm into m � 9. 3 x 10 -5 g into μg � 4. 0 x 105 g into kg

More Complex � 1. 46 kg/L into g/L � 8. 02 g/m. L into Dag/c. L � 5. 42 g/cm 3 into cg/c. L � 2. 734 cg/L into ng/m. L

Using Factor Label to solve problems �The density of copper is 8. 92 grams per centimeter cubed. How many cubic centimeters would 54 grams weigh? �The density of lead is 11. 3237 grams per cubic centimeter. What would the mass of 34. 2 cm 3 be?

Summarize what you know �What is one of the major benefits of the factor label method? �What are the 6 basic prefixes? �Summarize on your own.
