According to the rules for arithmetic operations with significant figures, if the mass of an object is \( 4.237 \text{ g} \) and its volume is \( 2.51 \text{ cm}^3 \), the density reported should be to how many significant figures?

  1. 2
  2. 3
  3. 4
  4. 11

Correct answer · Option 2

3

Explanation

In multiplication or division, the final result should retain as many significant figures as are there in the original number with the least significant figures (here 3.51 has 3). Thus density is reported to 3 significant figures.
