The equation to calculate Density is Mass / Volume. You are given that the density is 5.45 and the mass is 65; 5.45 = 65 / v. So v = 65 / 5.45; v = 11.93 mL (or if you want your answer to consider significant figures, v = 12 mL).

Taking into account the definition of density,  the volume of an object with a mass of 65 g and a density of 5.45 [tex]\frac{g}{mL}[/tex]  is 11.93 mL.

But first you must know the definition of density. Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. That is, the density of a material is the ratio of its mass to its volume.

The expression to calculate the density is:

[tex]density= \frac{mass}{volume}[/tex]

In this case, you know that:

  • mass= 65 g
  • volume= 5.45 [tex]\frac{g}{mL}[/tex]

Replacing in the definition of density:

[tex]5.45 \frac{g}{mL} = \frac{65 g}{volume}[/tex]

Solving:

5.45 [tex]\frac{g}{mL}[/tex]× volume= 65 g

volume= 65 g÷ 5.45 [tex]\frac{g}{mL}[/tex]

volume= 11.93 mL

Finally, the volume of an object with a mass of 65 g and a density of 5.45 [tex]\frac{g}{mL}[/tex]  is 11.93 mL.
