The mass and volume of a body are 4.237 g and 2.5 cm3, respectively. The density of the material of the body in correct significant figures is

RULES OF DIVISION IN SIGNIFICANT FIGURES:

(i)In division the answer is rounded off to the same number of significant figures as possessed by the least precise term used in the calculation.

(ii)The final result must contain as many significant figures as are in the original number with the least significant figures.

Here,

No. of significant figures in 4.237 is 4 and in 2.5 is 2. Here 2.5 is the least precise term used. Therefore, the answer must contain 2 significant figures.

Now, applying the rules and rounding off the answer we get
