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 meterial of the body in correct significant figures is

A

`1.6048 g cm^3`

B

`1.69g cm^(-3)`

C

`1.7 g cm^(-3)`

D

`1.695g cm^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
(c )
Density ` =(Mass)/(Volume) = (4.237)/(2.5) = 1.6948 g//c.c`
As per rules, the result of division will have two significant figures.
`:. Density = 1.7 g//c.c`.
