If a can of soup 150 g mass and 0.75g/ cm^3 density what’s the volume
Liula [17]

Answer:

<h3>The answer is 200 cm³</h3>

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 = 150 g

density = 0.75 g/cm³

We have

volume =  \frac{150}{0.75}  \\

We have the final answer as

<h3>200 cm³</h3>

Hope this helps you
