Answer
4.5 g cm⁻³

The correct answer is 4.5 g cm⁻³ — Step 4: Write the result with units: 4.5 g cm⁻³.

Step-by-step solution

  1. Step 1: Recall the formula for density: density = mass ÷ volume.
  2. Step 2: Substitute the given values: density = 0.45 g ÷ 0.1 cm³.
  3. Step 3: Perform the division to get 4.5.
  4. Step 4: Write the result with units: 4.5 g cm⁻³.
Common mistake: Dividing mass by volume incorrectly or misplacing decimal point.
