Question

The mass and volume of a body are 2.537 g and 3.7 cm3, respectively. The density of the material of the body in correct significant figures is ___.

Answer 1

Answer:

685.68kg/m3

Explanation:

To find the density of a substance it is best to measure in standard units like kilograms,metres and others.

Density =mass/volume

The mass is given in grams so you change it into kilograms and the centimeters to meters

It implies that

2.537g =2.537 x 10^-3

and 3.7cm^3 =3.7 x 10^-6

So hence Density = 2.537 x 10^-3/3.7 x 10^-6

Density = 685.68kg/m^3
