Explanation:
Titration is a process of adding one concentration of solution to another solution until the reaction neutralizes. In acid base titration the concentrated acid solution is titrated with concentrated base solution. Ph indicator is used to monitor the reaction. When reaction neutralizes it changes its color to pink indication that the reaction is completed.
The density of the rubber ball is calculated by the mass of the rubber ball divided by the volume of the rubber ball.
21mL-15mL=6mL which is the volume of the rubber ball
D=10g/6mL
D=1.666g/mL density of the rubber ball
