Answer:
density=mass/volume.
density=14/18
=0.777777777 ~ 0.8g/ml.
It will float because the it lesser than the density of water.

B
Electrons are found in shells or orbitals that surround the nucleus of an atom
pH is an important parameter for many reactions to take place in solution and in biological systems. It is related to the concentration of H⁺ ions through the following expression:
pH = 1/[H⁺] = -log [H⁺]
Wanting to know the pH of a solution is equivalent to knowing the amount of hydrogen ions present. But the pH scale is more convenient than the concentration scale because pH usually takes values between 0 and 14.
- When pH < 7 the solution is acid.
- When pH = 7 the solution is neutral (like pure water).
- When pH > 7 the solution is basic.
