Answer:
a. 4 g/mL
Explanation:
First, we need to find the volume of the object. The volume is equal to the volume of the water displaced. So, it can be calculated as the difference in the volumes
75 mL - 50 mL = 25 mL
Then, the volume of the object is 25 mL and the mass is 100 g. Now, we can calculate the density as follows
density = mass/volume
density = 100 g/25 mL
density = 4 g/mL
Therefore, the answer is
a. 4 g/mL
