Question

2.) 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? (1 point) 58.8 °c 56.3 °c 59.1 °c 59.0 °c 58.5 °c

Explanation:

Step1: Identify the out - lier

Precision means that the data points are close to each other. We look for the value that is furthest from the others.
The values 58.8 °C, 59.1 °C, 59.0 °C, 58.5 °C are relatively close. The value 56.3 °C is significantly different from the rest.

Answer:

56.3 °C
