Partial Pressure Calculator
Top
Pressure is the force per unit area acting on the walls of the container. Partial pressure is all about pressure exerted by the gas when that particular gas alone is present in the container.
Here there are two Partial Pressure Calculator
  1. One calculates the partial pressure if concentration of solute and Henry's Constant are given.
  2. Other Calculates the partial pressure if mole fraction and Henry's Constant are given.

Henry's constant kH with different units are given below in the table which helps in doing the manual calculations.

 Element  Henry Constant kH in
 $\frac{L atm}{mol}$
 Henry Constant kH in atm
 O2  769.23  4.259 $\times$ 104
 H2  1282.05  7.099 $\times$ 104
 Co2  29.41  0.163 $\times$ 104
 N2  1639.34  9.077 $\times$ 104
 He  2702.7  14.97 $\times$ 104
 Ne  2222.22  12.3 $\times$ 104
 Ar  714.28  3.955 $\times$ 104
 Co  1052.63  5.828 $\times$ 104

 

Steps for Partial Pressure Calculator

Step 1 :  

Read the given problem and list out the given quantities.



Step 2 :  

There are two formulas to Calculate the partial pressure p
If Concentration of the solute is given use the formula
                                                                 p = kH C


Where kH = Henry's law Constant,
C is the Concentration of the Solute.



If mole fraction of the solute is given then
                                                            p = kH x


Where kH = Henry's law Constant


x = Mole fraction of the Solute.


Substituting the values in the formula, we get the answer.

  1. Find the Partial pressure of N2 containing 0.75 mol in a given mixture?


    Step 1 :  

    Given: Concentration of solute C = 0.75 mole
    Henry Constant for mole fraction for N2, kH = 9.077 $\times$ 104 atm.



    Step 2 :  

    Since the Concentration of the solute is given we use the formula:
    p = kH C


       = 9.077 $\times$ 104 $\times$ 0.75


       = 6807.75  atm.



    Answer  :  

    The Partial pressure for N2 is 6807.75  atm.



  2. Find the Partial pressure of Ne having mole fraction of 0.12 in a given mixture?


    Step 1 :  

    Given: Mole fraction, x = 0.12
    Henry Constant for mole fraction for Ne, kH = 12.3 $\times$ 104 atm.



    Step 2 :  

    If mole fraction of the solute is given then
    p = kH x


       = 12.3 $\times$ 104 $\times$ 0.12


       = 14760 atm.



    Answer  :  

    The Partial pressure for Ne is 14760 atm.
