There will be an information festival on Monday Dec. 19th. You are allowed an 8.5 X 11 inch (21.59 cm x 27.94 cm) hand written "reference sheet" that you will hand in with your information festival for 5 points. You must make the reference sheet your self, you can't increase surface area by any means, and you can't zerox a friends reference sheet. Material from Quarter 2 will be the focus but you should know material from quarter one.

Accuracy vs. Precision
Precision: Measurements are said to be precise if they yield very similar results when repeated in the same manner.
Accuracy: A measurement is considered accurate if it yields a result that is very close to the true or accepted value.

What is the formula for density?

What is the density of a marble that causes the water in a graduated cylinder to go from 110 ml to 150 ml and has a weight of 70 grams?
Which liquid is less dense and would float on top, fresh water or salt water?
See images bellow!!!!! Here is the link to the chapter if you need it.
Experimental Determination of Density Using Water Displacement A piece of rebar is weighed and then submerged in a graduated cylinder partially filled with water, with results as shown. (a) Use these values to determine the density of this piece of rebar.
(b) Rebar is mostly iron. Does your result in (a) support this statement? How?
SolutionThe volume of the piece of rebar is equal to the volume of the water displaced:
volume=22.4 mL−13.5 mL=8.9 mL=8.9 cm3(rounded to the nearest 0.1 mL, per the rule for addition and subtraction)
The density is the mass-to-volume ratio:
density=mass / volume=69.658 g / 8.9 cm3=7.8 g/cm3(rounded to two significant figures, per the rule for multiplication and division)
Check Your Learning An irregularly shaped piece of a shiny yellowish material is weighed and then submerged in a graduated cylinder, with results as shown.
