<u>Answer:</u> The partial pressure of hydrogen is 93.9 kPa.
<u>Explanation:</u>
To calculate the partial pressure of hydrogen, we will follow Dalton's Law.
This law states that the total pressure of a mixture of gases is equal to the sum of the individual pressures exerted by the constituent gases.
Mathematically,
![p_{total}=p_A+p_B](https://tex.z-dn.net/?f=p_%7Btotal%7D%3Dp_A%2Bp_B)
According to the question,
![p_{total}=p_{H_2O}+p_{H_2}](https://tex.z-dn.net/?f=p_%7Btotal%7D%3Dp_%7BH_2O%7D%2Bp_%7BH_2%7D)
We are given:
![p_{H_2}= ?kPa](https://tex.z-dn.net/?f=p_%7BH_2%7D%3D%20%3FkPa)
Putting values in above equation, we get:
![p_{H_2}= 93.9kPa](https://tex.z-dn.net/?f=p_%7BH_2%7D%3D%2093.9kPa)
Hence, the partial pressure of hydrogen is 93.9 kPa.
