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

Options

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

Answer

(c )

Explanation

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`.
