Answer:
Best answer choice is "Mass of the graduated cylinder with the liquid in it "
Explanation:
if they want to determine density of liquid they'll use D= m/v
- they already have the volume (v)
- now they just need the mass (m) of the liquid (BUT NOT OF THE CYLINDER) You'll want the LIQUID'S mass (m) ONLY
- So "Mass of the graduated cylinder with the liquid in it" = Liquid's mass WITH the cylinder's mass ALSO, let's get rid of the cylinder's mass
- now you get the liquid's mass by itself
- mass of graduated cylinder with liquid in it subtracted by the Mass of empty graduated cylinder = (m) mass of liquid
- (m) mass of liquid ÷ (v) volume of liquid in the graduated cylinder = (D) Density
- So your answer will be "Mass of the graduated cylinder with the liquid in it"
