STP stands for the Standard Temperature and Pressure. The standard temperature is 273 Kelvin or 0 degrees Celcius or 32 Fahrenheit and the standard pressure is 1 atm pressure or 760 mmHg, or 10,325 Pascals. STP is most commonly used when performing calculations on gases.

Answer : The concentration of 
ion, pH and pOH of solution is, 
, 1.05 and 12.95 respectively.
Explanation : Given,
Concentration of 
ion = 0.090 M
pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.
The expression used for pH is:
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
First we have to calculate the pH.
The pH of the solution is, 1.05
Now we have to calculate the pOH.
The pOH of the solution is, 12.95
Now we have to calculate the concentration.
![pOH=-\log [OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D)
![12.95=-\log [OH^-]](https://tex.z-dn.net/?f=12.95%3D-%5Clog%20%5BOH%5E-%5D)
![[OH^-]=1.12\times 10^{-13}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.12%5Ctimes%2010%5E%7B-13%7DM)
The concentration is,
here is some facts
Limestone is a sedimentary rock, whereas marble is metamorphic. These two rock types can be distinguished by their textures. ... 2- Gabbro and basalt are two igneous rocks having the same chemical composition, and the same minerals (plagioclase feldspar + pyroxene), but are of different origins.
