Question

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 °

Answer 1

Option (e) should be discarded.

Step-by-step 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.
