the denisty of copper is 8.96g/cm3. A sample of a metal mass of 40.0g and a volume of 6.0 cm3 what can you determine about the sample?
The sample's density, 6.67 g/cm^3, is less than that of copper. Therefore it is not copper. It isn't any other heavier metal or alloy than copper, either.
Wow how did you figure that out?
To determine what you can infer about the given sample, you need to compare its characteristics with those of copper and consider the density of copper.
The density of a substance is calculated by dividing its mass by its volume. In this case, the density of copper is given as 8.96 g/cm³.
Given information:
Mass of the metal sample = 40.0 g
Volume of the metal sample = 6.0 cm³
1. Using the given information, you can calculate the density of the metal sample by dividing the mass by the volume:
Density of the metal sample = Mass / Volume = 40.0 g / 6.0 cm³
2. Calculate the density using the given values:
Density of the metal sample = 6.67 g/cm³
Now, let's compare the density of the metal sample (6.67 g/cm³) with the density of copper (8.96 g/cm³):
Since the density of the metal sample is less than the density of copper, it indicates that the sample is not made of pure copper. It could be a copper alloy or a different metal altogether.
Based on this analysis, you can determine that the given metal sample is not pure copper due to its lower density compared to the density of copper.
