Answer: 5.789 grams per milliliter (g/mL).
Step-by-step explanation:
The density of an object can be calculated using the formula:
Density = Mass / Volume
Given the values:
Mass = 72 g
Volume = 4.56 mL
Density = 72 g / 4.56 mL
Density ≈ 15.789 g/mL
So, the density of the object is approximately 15.789 grams per milliliter (g/mL).
