Subtract the mass of the empty graduated cylinder from the mass when full. This will give the mass of the fluid or 92.42 g. Now divide this number by the volume which will give you the density: 1.21 g/mL.
Question 2
The measuring cup measures in mL of volume. What you must do is convert the mass of the Canola oil to mL of Canola oil. This is done by dividing the density into the mass number. This will give you 230 mL. Hence measure out 230 mL of Canola oil and you have 200 g.
