Question

Hailey, a chemistry student, is measuring samples of a metallic substance for an experiment on density, using a balance that measures to 1/10 of a gram. Which is the most accurate measurement based on the limitations of the balance that might be found in her recorded data? A) 9.01 grams B) 9.2 grams C) 9.24 grams D) 9.244 grams

Answer 1

B) 9.2 g

Explanation:

The balance measures only to 0.1 g.

So, the best measurement Hailey can make is to the nearest 0.1 g.

The most precise measurement she can make is 9.2 g.

The accuracy depends on the balance and on how carefully she works.
