#color(red)("10.g/mL"#

Explanation:

Let's use the equation below to answer this question:

We have the volume and mass, but the mass doesn't have the appropriate unit associated with it. To go from kilograms to grams we have to use the following relationship:

Multiply 2.7 kg by 1000 like this:

#2.7cancel"kg"xx(1000g)/(1cancel"kg")# =2,700g

Now, just plug your known values into the equation and solve for density:

#(2,700g)/(270mL)# = 10. g/mL

Thus, that object has a density of 10. g/mL
