8) What is the density of an unknown liquid if 34.8 grams
occupies 12mL? (Include units)
Essential Question: What are pennies made of?
How can we use density to help us find out?
Select 10 pennies from each container and make
sure to separate 10 1982 and before.
Density Problems

If 25.6 grams of a substance has a volume of
5.7 mL, what is the substance? How do I
know how to round it off?
25.6 g = 4.49122807 = 4.5 to sig figs
5.7mL

What mass of aluminum occupies 18.98cm3 ?
Use yellow packet find density of aluminum
D = m/v
2.702g/ml = m/18.98cm3
m = 51.28 grams
Unit Essential Question: What is density?
Daily EQ: Can we graph density?
Warm-up 9/4/13
1) What is the density of 78 grams of aluminum
that has a volume of 28.87mL?
2) How many grams of gold were found in the
ship wreck if it occupied 435cm3 of space
(density of gold is 19.31 g/cm3) ?
Penny Lab
1) Select 10 Pre-82 pennies and 10 ‘83 and
newer
2) Determine the density of each set of pennies.
You can use either method to determine
volume.
3) Find the metal on page R-47 through R-49
Make sure it sounds like a reasonable metal
4) What other physical or chemical properties
could we use to make the final distinction
