KOH -------------> K⁺ + OH⁻
pOH = - log [ OH⁻ ]
pOH = - log [ 1 x 10⁻⁵ ]
pOH = 5
pH + pOH = 14
pH + 5 = 14
pH = 14 - 5
pH = 9

Ideal gases are hypothetical gases whose molecules occupy negligible space and have no interactions, and that consequently obeys the gas laws exactly.
Not exactly sure about the amount...
I hope this helps! :)
Explanation:
A heterogeneous mixture has particles that are not uniformly distributed, but a homogeneous mixture has particles that are uniformly distributed.
They don't react with other elements under normal conditions as they are already in a low energy or stable state
