[H+] = Kw / [OH-] = 1.0*10-14 / 2.5*10-4 = 4.0*10-11 mol/L
60j + 2z = 6
- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.

What is the number of integral solution to x plus y plus z equals 100?
The solution is (x, y, z) = (2.5, 1, 2.5).
60j + 2z = 6
A solvent plus a solute equals a solution.
p = -log[H+] = 12.4
- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.

What is the number of integral solution to x plus y plus z equals 100?
13.7 take the negative logarithm
The answer is (3.5)2 plus (4)2 equals 410.
The solution is (x, y, z) = (2.5, 1, 2.5).
It can't be solved because its discriminant is less than zero
-10
pH means -log10(H+concentration) so pH of a H+ concentration 3.6x10-9 is: pH = -log10(3.6x10-9) ≈ 8.4
