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.

Answer:

56.0°C

Explanation:

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

Average = [tex]\frac{number 1 + number 2 + number 3 + number 4 }{4}[/tex]

Average temperature = [tex]\frac{56.0C +  55.0C +  57.5C +  55.5C}{4}[/tex]

                                    =  [tex]\frac{224}{4}[/tex] = 56.0°C

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