slope m= (y2−y1) (x2−x1)
Volume V = length l × width w × height h
mass m = density ρ × Volume V
ρ= m V

  1. The first graph shows data gathered by a student in SC 130 physical science. Soap density background rectangle major grid lines axes x-axis and y-axis linear regression line data points as circles text layers Soap density volume (cm3) mass (g) y-axis labels 0 12 24 36 48 60 72 84 96 108 120 x-axis labels 0 10 20 30 40 50 60 70 80 90 100
    __________ _____ Calculate the density ρ of the soap (include units!).
  2. ______________ Will the soap float or sink?
  3. __________ _____ A student measures a bar of soap with a length of 5 cm, a width of 3 cm, and a height of 2 cm. What is the volume of the soap?
  4. __________ _____ A student measures a bar of soap with a length of 5 cm, a width of 3 cm, and a height of 2 cm. The soap has a mass of 36 grams. What is the density of the soap?
  5. ____________________ A student measures the length of a piece of soap using a ruler. Is the measurement a primary or calculated measurement?
  6. ___________ _____ A bar of soap is found to have a density of 1.6 g/cm³. If the volume of the soap is 100 cm³, what is the mass of the soap?
  7. density vials ________________ The three identical vials in the image each have a volume of 14.0 cm³. Two of the vials are floating, one sank. Which of the vials has a mass of 13.3 grams, the floating vials or the sinking vial? blogger icon
  8. ___________ _____ A lead cube is found to have a density of 11.4 g/cm³. If the mass of the cube is 365 grams, what is the volume of the cube??
  9. In laboratory 012 the bar of soap was predicted to float or sink. When the prediction was tested by putting the bar of soap into water, the bar of soap somehow knew what to do. Why do you think the bar of soap knew what to do?
