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. A
    2
  2. B
    3
  3. C
    4
  4. D
    11
View Answer & Solution

Correct answer · Option B

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.

According to the NCERT rounding-off rules, the numbers \( 3.745 \) and \( 3.735 \), when rounded off to three significant figures, become respectively:→A spherical surface area element \( dA = 0.25\text{ m}^2 \) at a distance \( r = 0.5\text{ m} \) from the center subtends a solid angle \( \Omega \). An arc of length \( ds = 0.2\text{ m} \) on a circle of the same radius \( r = 0.5\text{ m} \) subtends a plane angle \( \theta \). The ratio of the numerical value of \( \Omega \) (in steradians) to \( \theta \) (in radians) is:→As illustrated in Fig. 1.1(b), a solid angle \( d\Omega \) is defined as the ratio of intercepted area \( dA \) of a spherical surface to the square of its radius \( r^2 \). A flat circular disc of radius \( R \) is placed perpendicular to the axis at a distance \( d = \sqrt{3}R \) from an apex \( O \). The solid angle subtended by the disc at the apex \( O \) is:→A substance of mass \( 5.74\text{ g} \) occupies a volume of \( 1.2\text{ cm}^3 \). Keeping the significant figures in view, its density should be expressed as:→
