The density of zinc is approximately 7.14 g/cm³ at 20°C. This means that one cubic centimeter of zinc has a mass of 7.14 grams. Different sources may report slightly varying figures due to measurement differences and temperature variations. For instance, some sources cite values like 7.133 g/cm³ at 25°C. However, 7.14 g/cm³ remains a widely accepted and accurate approximation.
Understanding Density
Density is a measure of how much mass is contained within a given volume. It's a fundamental physical property of matter, and for zinc, this density value reflects its atomic structure and packing within the solid metal.
Several sources corroborate this density value:
- American Elements: Reports a density of 7.14 g/cm³ at 20 °C. Zinc Metal | AMERICAN ELEMENTS ® www.americanelements.com › zinc-metal-7440-66-6
- Florida State College Jacksonville: Lists zinc's density as 7.14. https://web.fscj.edu/Milczanowski/psc/lect/Ch4/slide6.htm
- Wikipedia: Provides a density of 7.140 g/cm³. https://en.wikipedia.org/wiki/Zinc
- Royal Society of Chemistry: States the density as 7.134 g cm⁻³. https://www.rsc.org/periodic-table/element/30/zinc
- Britannica: Gives a density of 7.133 grams/cm³ at 25 °C. https://www.britannica.com/science/zinc
The slight variations are likely due to factors like the purity of the zinc sample and temperature fluctuations during measurement.
