Neutral pH means a pH of 7, yes? Recall that 'pH' means the POWER of Hydrogen. You should be familiar with the equation : pH = -log[H+].
In this case, 7 = log[H+].
Mathematically rearranged, this means that to find H+ concentration,
[H+] = 10 ^-pH.
In this case, [H+] = 10 ^-7.
I am assuming this is conducted at a standard 25 degrees. The auto-dissociation formula of water is this: Kw = [H3O+] x [OH-] at 25 degrees.
The concentration of Hydronium is the same as the concentration of hydrogen, 10 ^-7. mol/L.
There's your answer!
the floor isnt clean until the soap is removed so the soaps dirty
Explanation:
When an acid is dissolved in water it forms hydrogen ions (H+) that combine with water to form the hydronium ion (H3O+) .
Answer:- 17.1 is the average atomic mass.
Solution:- To calculate the average atomic mass we convert the given percent abundances to the decimals and multiply by their restive isotopic masses and take the sum of all these.
Average atomic mass = 16.0(0.20)+17.0(0.50)+18.0(0.30)
average atomic mass = 3.20+8.50+5.40
average atomic mass = 17.1
Therefore, the average atomic mass is 17.1.
