Answer:
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 .
