Final answer:
To identify a sample using mass and volume measurements, calculate the density of the sample. Compare the calculated density to known densities of substances to determine the identity of the sample.
Step-by-step explanation:
To identify a sample using mass and volume measurements, the student can calculate the density of the sample. Density is a physical property that can help identify different substances. The formula for density is Density = Mass/Volume. By measuring the mass and volume of the sample, the student can calculate its density and compare it to known densities of substances to determine the identity of the sample. For example, if the density of the sample is close to the known density of water (1 g/cm³), it could be identified as water.
