Question
Chapter F, Problem A.26E
Interpretation Introduction
Interpretation:
The answer of the given calculation has to be expressed in correct number of significant figures.
Concept Introduction:
Whenever a measurement is made, the significant figures in the measured quantity give the actual measurement. For this the significant figures should be recognized first. The significant figures may be non-zero digit and zero digit. But Zero may be or may not be a significant figure. The number of significant figures in the answer after solving a multiplication or division problem is same as the number of fewest significant figures present in the measurement.

Perform the following arithmetic operations, and report the result to the proper number of significant figures:(a) 105.5 L + 10.65 L, (b) 81.058 m − 0.35 m, (c) 3.801 × 1021 atoms + 1.228 × 1019 atoms, (d) 1.255 dm × 25 dm, (e) 139 g ÷ 275.55 mL.
How many significant figures would this calculation have if it were completed: (9.04 - 8.23 + 21.954 + 81.0) × 3.1416
Express the following sum with the correct number of significant figures: 1.9m + 142.5cm + 6.27 * 10 ^ 5 μm.
