Considering the following two volume measurements: 57.7 ml and 57.68ml. which of these is the more precise?

The more precise measurement is 57.68 mL

Explanation:

Precision refers to the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 3.2 kg each time. Then the measurement is very precise.

Level of precision is determined by the maximum number of decimal places.

According to question:

Measurement 1 = 57.7 mL

Measurement 2 = 57.68 mL

The maximum number of decimal places are 2. So, the level of precision for the given question is 0.01 mL. So, the measurement having maximum decimal places will be more precise.

Hence, the more precise measurement is 57.68 mL

c is the answer because when something is left after something evaporates that shows the chemical change.
