You should contact apple about that!
M=D*V
D=10.5 g/cm³
V=42.5 cm³
m= 10.5 g/cm³ * 42.5 cm³ ≈ 446 g
m≈446 g
Answer:Base A is the weakest conductor electricity
Explanation:
Dissociation is a factor that affects electrical conductivity. The greater the percentage of dissociation for bases the stronger the conductivity of electricity.
Given that
Base A dissociates 25% in water
Base B dissociates 50%.
Base C dissociates 75%
We can conclude that Base A is the weakest conductor oelectricity since it has the lowest percentage of dissociation.
1:3
The ratio of Al3+ ions to Cl− ions in the chemical formula is 1:3.
