11-3 DENSITY GRADED ASSESSMENT
  • Solve the following problems.
  • Show your work.
  • Type your answer in the numerical answer field (round to sig figs), then type one space, then type your units. If your answer is a decimal, include the leading zero (the zero before the decimal point). Example: 0.25 g/mL
  • You will be asked to "sign" the honor code at the end.
1

Calculate the volume of 350 g of lead (Pb) given that the density of lead is 11.35 g/cm3.

1

Given that the density of mercury (Hg), the only liquid metal, is 13.6 g/mL, would the mass-volume line for Hg be above or below the line for lead (Pb)?

1

Given that the density of mercury (Hg), the only liquid metal, is 13.6 g/mL, would lead sink or float in/on mercury?

1

Does density depend on how much of the substance is present?

a) Sketch a graph of the density of water.
b) On the same set of axes, sketch a line that would represent the density of aluminum (Al), 2.7 g/cm3. NOTE: your line for Al does not have to be perfect, but should be a reasonable approximation.
c) Make sure I can tell which line is for which substance.

1

Using your graph, what is the mass of 5 cm3 of Al? Do not do a calculation.

1

Refer to your density graph, what are the units for the slope of the line.

1

Draw two squares. The square on the left represents water and the square on the right represents aluminum. Using circles to represent the particles, draw water and aluminum on the particle level.
