Concept explainers
(a)
Interpretation:
Calculations have to be carried out for
Concept Introduction:
Significant figures: The digits that are measured in a number including one estimated digit are called as significant figures.
The answers for those calculations that involve multiplication and division will have the same number of significant figures as the original number with the fewest number of significant figures.

- Two students were assigned to determine the mass of a sample of an unknown liquid. Student A used an ordinary laboratory balance that could determine mass to ±0.01 g. Student B used an analytical balance that could measure mass to ±0.1 mg. Each made four measurements, giving the following results: Student A: 8.19 g, 8.22 g, 8.21 g, 8.25 g Student B: 8.2210 g, 8.2210 g, 8.2209 g, 8.2210 g 2. Which student is more precise?
