A 25.2-mL sample of kerosene was determined to have a mass of 20.41 g. What is the density of kerosene?
To calculate the density, we'll use the formula below:
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,
The volume can have units of
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:
Thus, that sample of kerosene has a density of 0.810 g/mL.
