To analyze the unknown substance found on Mars, we can start by calculating its density, which will help in identifying the material.
The formula for density (\( \rho \)) is:
\[ \rho = \frac{\text{mass}}{\text{volume}} \]
Given:
- Mass = 4725 grams
- Volume = 350 cm³
We can plug these values into the formula:
\[ \rho = \frac{4725 , \text{g}}{350 , \text{cm}^3} \]
Calculating that gives:
\[ \rho = 13.5 , \text{g/cm}^3 \]
This calculated density of 13.5 g/cm³ can help scientists compare it with known materials to identify the unknown substance. For context, here are the densities of a few common substances:
- Lead: ~11.34 g/cm³
- Gold: ~19.32 g/cm³
- Iron: ~7.87 g/cm³
- Water: ~1 g/cm³
Given the density of the substance is 13.5 g/cm³, it is denser than lead but less dense than gold. The nature of the substance could provide clues about its composition, possible mineral content, or other characteristics. Further analyses such as chemical tests, spectroscopy, or X-ray diffraction might be needed to determine its exact properties and identity.
