Answer:

#color(magenta)("2.70 g/mL")#

Explanation:

To calculate the density, we have to 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, #g#.

  • The volume will have units of #mL# or #cm^3#

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

#Density =(40.5g)/(15.0mL)#

Thus, the block of aluminum has a density of 2.70 g/mL.
