Physics · UNITS AND MEASUREMENT

A substance of mass \( 5.74 \text{ g} \) occupies a volume of \( 1.2 \text{ cm}^3 \). Express its density to the correct number of significant figures, and identify the underlying rule.

1. \( 4.8 \text{ g cm}^{-3} \), as the result should retain as many significant figures as the input quantity with the least significant figures.
2. \( 4.78 \text{ g cm}^{-3} \), as the result should retain as many significant figures as the input quantity with the maximum significant figures.
3. \( 4.783 \text{ g cm}^{-3} \), as arithmetic division allows up to 4 significant figures.
4. \( 5.0 \text{ g cm}^{-3} \), after rounding off to the nearest integer.
