Question

If an object has a mass of 39g and density of 3 g/ml, what is its volume?

Answer 1

Hello!

To find the volume with a known mass and known density:

⇒ must consider the relationship between all three of the variables:

`\hookrightarrow \text{Mass = volume * density}`

Let's write down all that we know:

• Mass: 39g
• Density: 3g/ml

Let's plug these into our equation:

`\text{Mass = volume * density}\\39\text{g} = \text{volume } *3\text{g/ml}\\\\ \text{volume} = \frac{39\text{g}}{3\text{g/ml}} \\\\\text{volume}=13\text{ml}`

Answer: 13 ml

Hope that helps!
