pH of solution = 9.661
<h3>Further explanation
</h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
pOH=-log[OH⁻]
![\tt pOH=-log[4.583\times 10^{-5}]\\\\pOH=5-log~4.583=4.339](https://tex.z-dn.net/?f=%5Ctt%20pOH%3D-log%5B4.583%5Ctimes%2010%5E%7B-5%7D%5D%5C%5C%5C%5CpOH%3D5-log~4.583%3D4.339)
pH+pOH=pKw

Sorry but it depends on the gas in question and it's temperature of condensing /boiling point if this it 0° it will turn liquid
Explanation:
Average atomic mass of the vanadium = 50.9415 amu
Isotope (I) of vanadium' s abundance = 99.75 %= 0.9975
Atomic mass of Isotope (I) of vanadium ,m= 50.9440 amu
Isotope (II) of vanadium' s abundance =(100%- 99.75 %) = 0.25 % = 0.0025
Atomic mass of Isotope (II) of vanadium ,m' = ?
Average atomic mass of vanadium =
m × abundance of isotope(I) + m' × abundance of isotope (II)
50.9415 amu =50.9440 amu× 0.9975 + m' × 0.0025
m'= 49.944 amu
The atomic mass of isotope (II) of vanadium is 49.944 amu.
Using PV=nRT
you get 268.976268L
=270L
It is easiest to tell if a solution is saturated if there is residue on the bottom. If it crystallized, the solution is saturated. If it is a supersaturated solution, there will not be crystallization unless more of the solute is added, at which point all of it will crystallize.
