Answer:

#color(purple)("The mercury metal has a mass of 48.3g."#

Explanation:

To calculate the mass of the object, we have to use the following formula:

- 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 density and volume, both of which have good units so all we have to do is rearrange the equation to solve for the mass:

#densityxxvolume=(mass)/(cancel"volume")xxcancel"volume"#

#color(coral)("Density")##xx##color(coral)("Volume = Mass")#

#(13.6g)/cancel"mL"xx3.55cancel"mL"#

Thus, the object has a mass of 48.3g.
