The density of the rock is 5 g/cm³. First Determine the volume of the rock: The volume of the rock is equal to the volume of water displaced, which is the difference between the final water level (70 mL) and the initial water level (50 mL). This gives us a volume of 20 mL.Convert the volume to cubic centimeters: Since 1 mL is equal to 1 cubic centimeter (cm³), the volume of the rock is 20 cm³.Calculate the density: Density is defined as mass divided by volume. In this case, the mass of the rock is 100 grams, and the volume is 20 cm³. Therefore, the density of the rock is 100 grams / 20 cm³ = 5 grams per cubic centimeter (g/cm³) Make this simpler

To determine the density of the rock, follow these steps:

  1. Calculate the Volume of the Rock:

    • Final water level: 70 mL
    • Initial water level: 50 mL
    • Volume of rock = Final level - Initial level = 70 mL - 50 mL = 20 mL
  2. Convert Volume to Cubic Centimeters:

    • Since 1 mL = 1 cm³, the volume of the rock is also 20 cm³.
  3. Calculate the Density:

    • Density is mass divided by volume:
    • Mass of the rock = 100 grams
    • Volume of the rock = 20 cm³
    • Density = Mass / Volume = 100 grams / 20 cm³ = 5 g/cm³

So, the density of the rock is 5 g/cm³, confirming the given density value.
