- Approximate densities at room temperature: - Milk: Approx. 1.03 g/cm³ (slightly denser than water). - Acetone: Approx. 0.79 g/cm³ (a lightweight organic solvent). - Red soil: Bulk density varies greatly but is typically in the range of 1.2 to 1.6 g/cm³ or higher, depending on composition and compaction. Even the solid mineral components 7.87 g/cm³ (a dense metal). - Comparing these values, Acetone (0.79 g/cm³) has the lowest density.
Which one of the following has the least density at room temperature?
