Answer:
The sample is fool's gold
Explanation:
Density is defined as the ratio between mass in grams and volume in mililiters.
A sample of pure gold has a density of 19.3g/mL.
Using Archimedes' principle, the volume of the sample is:
52.2mL - 47.5mL = 4.7mL
As the mass of the sample is 23.5g, the density is:
23.5g / 4.7mL = 5g/mL
The denisty of the sample is very different to density of pure gold, that means:
the sample is fool's gold
