Question

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?

Answer 1

56.0°C

Step-by-step explanation:

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

Average =
`(number 1 + number 2 + number 3 + number 4 )/(4)`

Average temperature =
`(56.0C +  55.0C +  57.5C +  55.5C)/(4)`

=
`(224)/(4)` = 56.0°C

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

Answer 2

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° The melting point should be an arithmetic average of these four or 56 degrees.
