Answer

Explanation:

Step1: Find mass of batteries in box

Subtract mass of box from mass of batteries + box. $837 - 92=745$ grams

Step2: Find mass of one battery

Divide mass of 9 batteries by 9. $\frac{207}{9}=23$ grams

Step3: Calculate number of batteries

Divide total mass of batteries in box by mass of one battery. $\frac{745}{23}\approx32.39$

Step4: Round using significant figures

Since 23 has 2 significant - figures, round 32.39 to 2 significant - figures. The answer is 32.

Answer:

32
