Answer:

#"density" = 1.85# #"g/cm"^3#

Explanation:

Well, if you know part 1, then the mass of the corn oil is #204# #"g"# (zero decimal places, as per rules of significant figures), and we're given its volume is #110.0# #"cm"^3#.

The equation for density is

#"density" = "mass"/"volume"#

We know:

  • #"mass" = 204# #"g"#

  • #"volume" = 110.0# #"cm"^3#

Plugging these in:

#"density" = (204color(white)(l)"g")/(110.0color(white)(l)"cm"^3) = color(red)(ulbar(|stackrel(" ")(" "1.85color(white)(l)"g/cm"^3" ")|)#

rounded to #3# significant figures.
