2. Since the slope is in g/mL it represents . . . . . DENSITY3.
Both E and F have the same number of particles. Since particles with larger size have greater mass, then E must have greater mass. Volumes appear equal so E has greater density.
(50, 80) 4.
a) Equal masses - Pans would be balanced since have
same mass on both sides.
Equal volumes - A pan would be tilted down
because it has greater mass in same volume. For
example at 10 mL, B would have mass of 5 g,
while A would be 17 g.
(60, 30)
(0, 0)
(0, 0)
b) Substance A
= 1.6 g/mL
Since the slope is in g/mL
it represents DENSITY
Substance B
= 0.5 g/mL

3. To balance, I would need 16 g of B
1.6 g of A
10 mL of A x
= 16 g of A
1 mL of A

e) Sketch a line with a slope of
f) Substance A will sink as it has a larger density (slope) than H2O
Accordingly, substance B will float as it has a smaller density (slope) than H2O
0.5 g of B

5. Hg
5) Titanium has a density of 4.54 g/mL
So mL of titanium has a mass of Cu
45.4 g
Copper has a density of 8.96 g/mL Ti
So mL of copper has a mass of
89.6 g
Mercury has a density of g/mL
So mL of copper has a mass of
135.5 g
67.75 g
So mL of copper has a mass of
