The melting point of a white solid substance was determined in four repeated trials to be 56.0°c, 55.0°c, 57.5°c, 55.5°
c. what temperature should be reported as the melting point as a result of these trials?

56.0°C

Explanation:

We have to take the average of the four repeated trials:

Average =

Average temperature =

                                    =   = 56.0°C

56.0°C should be reported as the melting point as a result of these trials.

they both have a y in them
