Question

What is the density of an object that has a volume of 245 ml and a mass of 193 grams?

Answer 1

`0.788 g/(mL)`

Explanation:

To calculate the density, we have to use the formula below:

`color(blue)( "Density = (Mass)/(Volume)"`

• Usually, density will have units of `g/(mL)` when dealing with a liquid or units of `g/(cm^3)` when dealing with a solid.

• The mass has units of grams, `g`.

• The volume can have units of `mL` or `cm^3`

We are given the mass and the volume, both of which have good units. All we have to do is plug the given values into the equation:

`Density =(193g)/(245mL)`

Thus, the object has a density of 0.788 g/mL.
