Kw = 1.219x10⁻¹⁴
kw = [H⁺] x [OH⁻]
in water [H⁺] = [OH⁻] therefore:
[H⁺] = √ kw
[H⁺] = √ <span>1.219x10⁻¹⁴
[H</span>⁺] = 1.104x10⁻⁷
pH = - log [H⁺]
pH = - log [ <span>1.104x10⁻⁷ ]
pH = 6.95
hope this helps!</span>
<u>Answer:</u> The equilibrium partial pressure of phosgene is 7.34 atm
<u>Explanation:</u>
The given chemical equation follows:

The expression of
for above equation follows:

We are given:
Equilibrium partial pressure of CO = 
Equilibrium partial pressure of chlorine gas = 

Putting values in above equation, we get:

Hence, the equilibrium partial pressure of phosgene is 7.34 atm
Molarity is defined as the number of moles of solute in 1 L of the solution.
Since the mass of the solute has been given we have to obtain the number of moles of solute
Number of moles = mass / molar mass
So we need to convert the mass to number of moles by dividing the mass by its molar mass.
The volume of the solution needs to be given in L but it has been measured in ml. Therefore volume in mL should be converted to L.
The molarity is found by dividing the number of moles by volume of solution in L
Answer is C)
