The mass and volume of a body are 4.237 ...

The mass and volume of a body are 4.237 g and `2.5cm^(3)` respectively. The density of the material of the body in correct significant figures is

A

`1.6048 g cm^(-3)`

B

`1.69 g cm^(-3)`

C

`1.7 g cm^(-3)`

D

`1.695 g cm^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
C
In multiplication the final result should retain as many significant figure as are there in the original number with the lest significant figure in this question, density should be reported to be significant figure
`"Density" = (4.237g)/(2.5cm^(3)) =- 1.6498`
As rounding off the number we get density `= 1.7`
