Answer:

#0.810 g/(mL)#

Explanation:

To calculate the density, we'll use the formula below:

# "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 =(20.41 g)/(25.2mL)#

Thus, that sample of kerosene has a density of 0.810 g/mL.
