The volume of object is 3.2 ml
Given:
Mass of the object = M = 9.6 g
Initial volume of liquid: [tex]V_1 = 10.0\ ml[/tex]
Final volume of liquid after displacement: [tex]V_2 = 13.2\ ml[/tex]
Total volume of the displaced object inside a graduating cylinder will be given as difference between the final volume and initial volume of the expanding object.
[tex]V = V_2-V_1 = 13.2 -1 0.0 = 3.2\ ml[/tex]
V = 3.2 ml
