Understanding Significant Figures in Measurements
📚 Example 1.2
5.74 g of a substance occupies 1.2 cm³. Express its density by keeping the significant figures in view.
Answer: There are 3 significant figures in the measured mass whereas there are only 2 significant figures in the measured volume. Hence the density should be expressed to only 2 significant figures.
Density = \(\frac{5.74}{1.2}\) g cm\(^{-3}\) = 4.8 g cm\(^{-3}\).
⚖️ Mass
Significant figures: 3
📏 Volume
Significant figures: 2
This simulation demonstrates how to calculate density while respecting significant figures. As shown in the example, when dividing measurements with different numbers of significant figures, the result should be expressed with the same number of significant figures as the measurement with the fewest.
Density Calculation
The density is expressed with 2 significant figures, matching the measurement with the fewest significant figures (volume).
