8.75 ml is added to a beaker containing 3.9 ml. What is the total volume of liquid in the beaker?

12.65 mL

Explanation:

From the question,

The initial amount of water already present in the liquid = 3.9 mL.

The, 8.75 mL of liquid is added to the breaker.

Now, to find the total volume of the liquid in the beaker can be determined by simply adding both the volumes, i. e. 3.9 mL and 8.75 mL.

hence,

the total volume in the beaker = 3.9 mL + 8.75 mL = 12.65 mL

Therefore, the total volume in the beaker = 12.65 mL.
