Question

Perform the following calculation and provide the answer with proper number of significant figures: (150.1 g) divided by (45.0 mL). Explain the reason for the number of significant figures.

Answer 1

To divide (150.1 g) by (45.0 mL) with the proper number of significant figures, we need to consider the number of significant figures in each measurement. Following the rules for multiplication and division with significant figures, we round the result to the same number of significant figures as the measurement with the fewest significant figures. Therefore, the answer is 3.34 g/mL.

Step-by-step explanation:

When dividing (150.1 g) by (45.0 mL), we need to consider the number of significant figures in each measurement.

The mass measurement has four significant figures, while the volume measurement has only three significant figures.

According to the rules for multiplication and division with significant figures, we should round the result to the same number of significant figures as the measurement with the fewest significant figures.

Therefore, the answer should have three significant figures, which gives us a result of 3.34 g/mL.
