Mass divided by Volume = Density
Find the density of the crown. 1.Is it real gold? 2.What is your evidence?
Graded for HONESTY & On
being COMPLETE
1. Go to: Pgs. 44-462. Use the information on those pages to
fill in #6-9 – Helpful hyperlink for illustrations on-line = less points
3. #9 Pg. 86 not 454. #10 – Show the math calculations for
glycerin, corn syrup and pancake syrup.
5. Show how the liquids would layer themselves in the graduated cylinder.
1. Identify the type of numbers you have. (unit labels)
2. Understand what the problem is asking.
3. It is a one step problem or two step problem?
4. Which formula should you use?
The following formulas are for finding different variables in density problems.
m mv D= =
= D vxm
D v
1. SAS Curriculum – DENSITY #11 –Should be done up to page 4
