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 .
