DENSITYDENSITY Slide 2 Review DENSITY_COMPUTATION slide found on
the SCIENCE weebly site. Graded Worksheet tom. Slide 3 DENSITY =
MASS / VOLUME DENSITY= grams/ mL or kg/L VOLUME= MASS / DENSITY
MASS= DENSITY X VOLUME Note: Higher density sinks/ stays at the
bottom and lower density stays on top/ floats. Slide 4 Lowest
Density = Lamp Oil Highest Density = Honey The substance that stays
on top has the lowest density and the substance that stays at the
bottom has the highest density. Slide 5 PROBLEM I 1. What is the
density of CO gas if 0.196 g occupies a volume of 100 ml? Slide 6
PROBLEM II 2) Mercury metal is poured into a graduated cylinder
that holds exactly 22.5 mL. The mercury used to fill the cylinder
weighs 306.0 g. From this information, calculate the density of
mercury. Slide 7 PROBLEM III 3. An irregularly shaped stone was
lowered into a graduated cylinder holding a volume of water equal
to 2 ml. The height of the water rose to 7 ml. If the mass of the
stone was 25 g, what was its density? Slide 8 PROBLEM IV 4. Silver
has a density of 10.5 grams/cm3 and gold has a density of 19.3
g/cm3. Which would have the greater mass, 5cm3 of silver or 5cm3 of
gold? Slide 9 PROBLEM V 5. Five mL of ethanol has a mass of 3.9 g,
and 5.0 mL of benzene has a mass of 44 g. Which liquid is denser?

0.196 g occupies a volume of 100 ml? Density= Mass/ Volume Density=
0.196g / 100 mL Density= 0.00196 g/ mL Slide 12 PROBLEM II 2)
Mercury metal is poured into a graduated cylinder that holds
exactly 22.5 mL. The mercury used to fill the cylinder weighs 306.0
g. From this information, calculate the density of mercury.
Density= Mass / Volume Density= 306 g/ 22.5 mL Density= 13.6 g/ mL
Slide 13 PROBLEM III 3. An irregularly shaped stone was lowered
into a graduated cylinder holding a volume of water equal to 2 ml.
The height of the water rose to 7 ml. If the mass of the stone was
25 g, what was its density? Density= Mass / Volume Density= 25 g/
(7 mL - 2 mL) = 25 g/ 5 mL Density= 5 g/ mL Slide 14 PROBLEM IV 4.
Silver has a density of 10.5 grams/cm3 and gold has a density of
19.3 g/cm3. Which would have the greater mass, 5cm3 of silver or
5cm3 of gold? Mass= Density x Volume Mass (silver)= 10.5 g/cm3 x 5
cm3= 52.5 cm3 Mass (gold)= 19.3 g/ cm3 x 5 cm3= 96.5 cm3 (greater)
Slide 15 PROBLEM V 5. Five mL of ethanol has a mass of 3.9 g, and
5.0 mL of benzene has a mass of 44 g. Which liquid is denser?
Density= Mass / Volume Density ethanol = 3.9 g/ 5 mL= 0.78 g/mL
Density benzene = 44 g/ 5 mL= 8.8 g/mL Benzene is denser than
ethanol. Slide 16 DENSITY OF WATER = 1 g/mL
