3)SAS Curriculum – Density #11 + Problems –Due Tomorrow.
4)Test #1 and Binder Check #1 – Due Thursday
Binder Check #1 & Test #11) Table of Contents is on-line
1) Edit out my notes to you2) Organize Papers in the order of the
ToC3) Number pages – Like a book
2) Test #1– Target Concepts on-line to review1) Create ½ page of notes, done by
hand, front side only2) You will have 1 class period to
complete the test

Density Formulas1) Identify the type of numbers you
are given in the word problem.2)Choose the correct version of the
Density formula1)Tip: If you are given the mass
you will always DIVIDE3)You may need to find VOLUME
first!
Problem #11) Henry has a block of an unknown element
with measurements of 5.8 cm on each side. It’s mass is 1645.9 grams. What is the element’s density? (10pts) – 2 step problem
Is cm a “volume” unit? (Look at the labels at the top of your
paper?
You will need to find volume 1st. What method will you use?
NO
Method #2 – LxWxH because it is a REGULAR shaped object

Problem #11) Henry has a block of an unknown element
with measurements of 5.8 cm on each side. It’s mass is 1645.9 grams. What is the element’s density? (10pts) – 2 step problem
195.11 cm3
5.8 x 5.8 x 5.8 =
Problem #11) Henry has a block of an unknown element
with measurements of 5.8 cm on each side. It’s mass is 1645.9 grams. What is the element’s density? (10pts) – 2 step problem
What type of number is “grams”? (Look at the labels at
the top of your paper?
Which version of the Density formula are you going to use….YOU have MASS and you’ve found the VOLUME?
Mass
D = m/v
Problem #11) Henry has a block of an unknown element
with measurements of 5.8 cm on each side. It’s mass is 1645.9 grams. What is the element’s density? (10pts) – 2 step problem
1645.9 divided by 195.11 =
Problem #4 – worth only 5 pts.
8.44 g/cm3
PROBLEMS – 7 AND 81) Remember – Density is how the particles are
packed.2) No matter the size(volume) of a substance…
the particles will be “packed” the same way3) Different substances have their particles
“packed” differently.4) Density is the comparison of these two
measurements
