Which metal has highest density ?

Options

A. Pt
B. Os
C. W
D. Hg

Answer

To determine which metal has the highest density among the given options, we will analyze the densities of each metal listed:

1. **Identify the metals**: The metals provided in the question are:
- Platinum
- Osmium
- Tungsten
- Mercury

2. **Understand density**: Density is defined as mass per unit volume (D = M/V). The higher the density, the heavier the metal will be for a given volume.

3. **Research the densities**: We need to find the densities of each of the metals mentioned:
- **Platinum (Pt)**: Density is approximately 21.45 g/cm³.
- **Osmium (Os)**: Density is approximately 22.59 g/cm³.
- **Tungsten (W)**: Density is approximately 19.25 g/cm³.
- **Mercury (Hg)**: Density is approximately 13.53 g/cm³.

4. **Compare the densities**: Now, we compare the densities of the metals:
- Platinum: 21.45 g/cm³
- Osmium: 22.59 g/cm³
- Tungsten: 19.25 g/cm³
- Mercury: 13.53 g/cm³

5. **Determine the highest density**: From the comparison, we can see that Osmium has the highest density among the metals listed.

6. **Conclusion**: Therefore, the metal with the highest density is **Osmium**.
