The question of whether mercury is heavier than tin hinges on understanding density, not simply mass. While a large chunk of tin might weigh more than a small amount of mercury, mercury is significantly denser than tin.

Density: The Key Factor

Density is defined as mass per unit volume (typically grams per cubic centimeter or g/cm³). A substance with a higher density packs more mass into a given space. This is the crucial factor in comparing the "heaviness" of two materials.

• Mercury (Hg): Has a density of approximately 13.5 g/cm³.
• Tin (Sn): Has a density of approximately 7.3 g/cm³.

As you can clearly see, mercury's density is almost double that of tin. This means that a cubic centimeter of mercury will weigh almost twice as much as a cubic centimeter of tin.

Practical Implications

This density difference has several practical implications:

• Liquid vs. Solid: Mercury is a liquid at room temperature, while tin is a solid. This doesn't directly affect density, but it influences how we interact with and utilize these metals.
• Applications: The high density of mercury makes it useful in applications requiring a heavy, liquid metal, such as certain types of switches and thermometers (although its toxicity is increasingly leading to its replacement). Tin's lower density and malleability make it valuable for food packaging, solder, and other applications.

Conclusion

While the weight of a sample depends on its volume, mercury is undeniably heavier than tin when comparing equal volumes due to its significantly higher density. This difference in density is a key factor influencing the practical applications of each metal.
