Explanation: -
Mass of the material = 45 grams
Volume of the material = 12
![cm^(3)](https://img.qammunity.org/2019/formulas/chemistry/middle-school/3hbdayk69nebtmi3jjybo6lumt43y9gk9w.png)
Density is defined as mass per unit volume.
Density of the material = Mass of the material / volume of the material
= 45 grams / 12
![cm^(3)](https://img.qammunity.org/2019/formulas/chemistry/middle-school/3hbdayk69nebtmi3jjybo6lumt43y9gk9w.png)
= 3.75 grams /
![cm^(3)](https://img.qammunity.org/2019/formulas/chemistry/middle-school/3hbdayk69nebtmi3jjybo6lumt43y9gk9w.png)
We see that the unit is grams /

Thus if the mass of a material is 45 grams and the volume of the material is 12 cm3, 3.75 gm /
would the density of the material .
