Final answer:
The density of the item is 25 g/cm³.
Step-by-step explanation:
Density can be calculated by dividing the mass of an object by its volume. In this case, the mass is given as 50g and the volume is given as 2cm³. To find the density, we divide the mass by the volume:
Density = Mass / Volume
So, Density = 50g / 2cm³ = 25g/cm³.
Therefore, the correct answer is a) 25 g/cm³.
