The density of the block is 5 g/mL
To solve the question given above, we'll begin by calculating the volume of the block. This can be obtained as follow:
Volume of water = 100 mL
Volume of water + block = 125 mL
Volume of block = 125 – 100
Finally, we shall determine the density of the block. This can be obtained as follow:
Volume of block = 25 mL
Mass of block = 125 g
Density = mass / volume
Density = 125 / 25
Therefore, the density of the block of is 5 g/mL
