Respuesta :
112.8 kpa, the reason for this is you subtract 3.2 Kpa from 116.0kpa and that's the answer.
Answer: The pressure of hydrogen alone is 112.8 kPa.
Explanation:
According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.
[tex]p_{total}=p_A+p_B[/tex]
Thus [tex]p_{total}=p_{H_2O}+p_{H_2}[/tex]
Given: [tex]p_{total}=116.0 kPa[/tex]
[tex]p_{H_2O}=3.2kPa[/tex]
[tex]p_{H_2}= ?kPa[/tex]
Thus [tex]116.0kPa=3.2kPa+p_{H_2}[/tex]
[tex]p_{H_2}=112.8kPa[/tex]
