Find the volume of an object that has a density of 3.14 g/mL and a mass of 52.9 g.
Natasha_Volkova [10]

Answer:

The answer is

<h2>16.8 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of object = 52.9 g

density = 3.14 g/mL

The volume of the object is

volume =  \frac{52.9}{3.14}  \\   = 16.847133757...

We have the final answer as

<h3>16.8 mL</h3>

Hope this helps you

Schach [20]

Answer:

3.7mL is the volume of the object

Explanation:

To convert the mass of any object to volume we must use density that is defined as the ratio between mass of the object and the space that is occupying. For an object that weighs 7.9g and the density is 2.28g/mL, the volume is:

7.9g * (1mL / 2.28mL) =
