Step-by-step explanation:
For one thing, Net volume = Final volume - Initial volume
The result of this calculation follows the rule of subtraction.
(For addition and subtraction problems, the answer should be rounded to the same number of decimal places as the measurement with the least number of decimal places.)
So, in case in point is:
Trial 2
Initial = 1.2 mL
Final = 2.45 mL
Net = 2.45 - 1.2 = 1.25 = 1.3 (follow the rule from above)
Please, take a look and apply the rule mentioned.
