A chemistry student is experimentally determining the boiling point of bromine. The experimental melting points are listed below from a to e. Which one should he discard so that he can say his data is precise?

a. 59.0 °C
b. 58.8 °C
c. 58.5 °C
d. 59.1 °C
e. 56.3 °C

Answer :

Answer:

Option (e) should be discarded.

Explanation:

The given set of data is said to be precise if the values are close to each other. In this problem, a chemistry student is experimentally determining the boiling point of bromine.

In this case, all values are close to each other but option (e) i.e. 56.3° should be discarded to make his data precise.
