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:
<em>the sample is fool's gold</em>
Answer:
1.8g
Explanation:
Initial volume = 43.5ml
Final volume = 49.4ml
Mass = 10.88g
Density = ?
Volume = Final volume - initial volume
= 49.4 - 43.5
= 5.9ml
Density = Mass/volume
Density = 10.88/5.9
= 1.8g/ml
