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
I'm a little rusty but I think its a Photon?
hope this helps!

Answer:
potential or pontenz Hydrogen is the negative logarithm of molar hydrogen ion concentration.
Explanation:
potential Hydrogen or potenz Hydrogen stands for pH
potenz is in german
