A cork has a mass of 3 grams and a volume of 16 cm³

Calculate the density.

Don't spam plzzz​

Answer 1

$\large\boxed{\rm{\blue{★Solution:}}}$

Density can be found by dividing the mass by the volume.

$\sf\rho= \dfrac{m}{v}$

•The mass of the cork is 3 grams and the volume is 16 cubic centimeters.

$\sf m= 3 \ g\\ \sf v= 16 \ cm^3$

Substitute the values into the formula.

$\sf\rho = \dfrac{3 \ g }{16 \ cm^3}$

Divide.

$\sf\rho=\dfrac {3}{16} \ g/cm^3$

$\sf\rho=0.1875 \ g/cm^3$

Thus,the density of the cork is :

${\boxed {\sf \dfrac{3}{16} g/cm^3}}$

or

$\boxed {\sf 0.1875 g/cm^3}$

Answer 2

Density of an object = mass/volume

Since,

mass of cork = 3g

volume of cork = 16 cm^3

Density of cork = 3/16 g/cm^3

Density of cork = 0.1875 g/cm^3
