Final answer:
The density of an object with a mass of 25 g and a volume of 2.0 cm³ is calculated to be 12.5 g/cm³, which corresponds to option A.
Step-by-step explanation:
To calculate the density of an object, you divide the mass of the object by its volume. Given that the mass of the object is 25 g and its volume is 2.0 cm³, we can use the density formula:
Density = Mass / Volume
Inserting the values:
Density = 25 g / 2.0 cm³ = 12.5 g/cm³
Therefore, the correct answer is A. 12.5 g/cm³.
