The density of pure silver is 10.5 g/cm3. Which one(s) of the following objects is (are) actually made of pure silver? SHOW YOUR WORK (just the formula work; use a calculator to do the math).
- A cube, which side measures 3.2 cm (32.768 cm3)

Answer

To determine if the cube is made of pure silver, we need to calculate its mass using the formula for density:

  1. Density formula: Density = Mass / Volume
  2. Rearrange to find Mass: Mass = Density × Volume
  3. Given: Density of silver = 10.5 g/cm³, Volume of cube = 32.768 cm³
  4. Calculate Mass: Mass = 10.5 g/cm³ × 32.768 cm³ = 344.064 g

If the mass of the cube is 344.064 g, it is made of pure silver.
