Question

Twelve glass beakers have a solution of hydrochloric acid of different quantities. The amount of solution, in milliliters, in each glass beaker is shown.

{15, 10, 16, 6, 20, 8, 22, 14, 9, 13, 27, 25}

What is the range in the quantity of hydrochloric acid?

Answer 1

21 milliliters

Explanation:

We first need to arrange the quantities from the least to the largest.

i.e {6, 8, 9, 10, 13, 14, 15, 16, 20, 22, 25, 27}

Range of this set of data is = largest quantity - least quantity = 27 - 6 = 21 milliliters

Answer 2

21

Explanation:

the range is the highest minus the lowest

27-6=21
