Calculate the solubility of hydrogen in water at an atmospheric pressure of 0.380 atm (a typical value at high altitude).
Atmospheric Gas Mole Fraction kH mol/(L*atm)
Ar
<u>Answer:</u> The solubility of hydrogen gas in water at given atmospheric pressure is
<u>Explanation:</u>
To calculate the partial pressure of hydrogen gas, we use the equation given by Raoult's law, which is:
where,
= partial pressure of hydrogen gas = ?
= total pressure = 0.380 atm
= mole fraction of hydrogen gas =
Putting values in above equation, we get:
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= partial pressure of hydrogen gas =
Putting values in above equation, we get:
Hence, the solubility of hydrogen gas in water at given atmospheric pressure is
