The density of magnesium is 1.7 g/mL. Predict the mass of a 400 mL block. WORK MUST BE SHOWN ON WHITEBOARD!
680 g
Predict the volume in cm3 of a block of aluminum that has a mass of 300 g. Density of aluminum is 2.7 g/cm3
111.1 cm3
the slope
List 3 important rules for making particle diagrams
Particles must be evenly distributed
Particles must differentiate between different substances
A box has a volume of 8.7in^3 and a area of 6.5in^2. Estimate the height in cm.
3.4cm
The density of platinum is 21.4 g/mL. Predict the mass of a 41890 mL block. WORK MUST BE SHOWN ON WHITEBOARD!
896,446 g
Predict the volume in mL of a block of lead that has a mass of 20.1 g. Density of lead = 11.3 g/cm3
1.78 mL
A has a density of 10 g/cm3, B has a density of 20 g/cm3. Which would have a steeper slope on a graph?
B because for an equal volume B has a greater mass, therefore a greater slope
Draw a particle diagram for a substance that has the density of 3g/1cm^3
must have 3 particles in the box
A box has a volume of 320cm^3 and a height of 10cm. Find the area. Show all your work!
19.5in^3= A x 3.9in
19.5in^3/3.9in = A
5in^2= A
A block of lead measured 0.89 cm on all sides. Predict the mass in grams. (density of lead= 11.3 g/cm3)

Predict the volume in m3 of a block of osmium that has a mass of 5000 g. Density of osmium = 22.6 g/cm3
For every 100 cm there is 1 m
0.00022 m3
You measured that 5 g of copper had a volume of 0.55 mL, then you measured that 20 g of copper had a volume of 2.40 mL. What is the density of copper?
Calculate slope: change in mass over change in volume= 8.1 g/mL
Metal A has a slope of 2g/1cm^3 and metal B has a slope of 5g/1cm^3. Draw the particle diagrams and explain which is denser.
B is denser than A because for an equal volume B has 5 particles and A has 2 particles.
The density of gold is 19.3 g/cm3. Predict the mass in kg of a block of gold that has an area of 20 cm2 and a height of 0.9 cm. (for every 1000 g there is 1 kg)
MUST SHOW ALL WORK ON WHITEBOARD!
0.3474 kg
Predict the mass in kg of a block of granite that measures 5 cm on all sides. Density of granite = 2.6 g/mL.
for every 1000 g there is 1 kg
0.048 kg
Substance A has a density ratio of 18g/1cm^3 and Substance B has the density of 48g/ 3cm^3. Draw particle diagrams for both substances and explain the relationship between the densities.
Substance A has 18 particles in the box. Substance B has 16 particle in the box. Substance A is more dense because for an equal volume A has 18 particles and B has 16.
Predict mass in pounds of a block of aluminum (density = 2.7 g/cm3) that measures 0.5 cm by 1 cm by 5 cm.
For every 1000 g there is 1 kg
For every 1 kg there is 2.26 pounds

Predict the volume in km3 of an iceberg that has a mass of 200,000 tons. Density of ice= 0.92 g/mL
1 ton= 2000 pounds
1 pound = 454 grams
1 cm3= 1 mL
1 km=1000 cm
