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

Options

A. 1.6048 g `cm^(-3)`
B. 1.69 g `cm^(-3)`
C. 1.7 g `cm^(-3)`
D. 1.695 g `cm^(-3)`

Answer

C

Explanation

In multiplication or division, the final resulat should retain as many significant figures as are there in the original numnber with the least significant figures. In this question, density should be reported to two significant figure.
density`=(4.237g)/(2.5cm^3)=1.6948`
As rounding off the number, we get density`=1.7`
