To determine the mass of an object given its density and volume, we use the formula: \[ \text{Mass} = \text{Density} \times \text{Volume} \] Given: - Density = 15 g/mL - Volume = 3 mL Substituting these values into the formula: \[ \text{Mass} = 15 \, \text{g/mL} \times 3 \, \text{mL} = 45 \, \text{g} \] Therefore, the mass of the object is 45 g, which corresponds to Option 2. **Explanation…Read More
