Calculate the volume of an object (in mL) if the density of the object is 4.08 g/mL and the mass of the object is 10.02 g.
slega [8]

Answer:

<h2>The answer is 2.5 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 = 10.02 g

density = 4.08 g/mL

The volume of the object is

volume =  \frac{10.02}{4.08}  \\  = 2.4558823...

We have the final answer as

<h3>2.5 mL to one decimal place</h3>
