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. `1.6048gcm^(-3)`
B. `1.69gcm^(-3)`
C. `1.7gcm^(-3)`
D. `1.695gcm^(-3)`

Answer

C

Explanation

Given, mass = 4.237g
Volume `=2.5 cm^(3)`
Density `=("Mass")/("Volume")=1.6948gcm^(-3)`
Here, volume has least number of significant figures, eqaul to two.
Density `=1.7 g"/"cm^(3)` (rounded off to two significant figures).
