Respuesta :
The partial pressure is the pressure exerted by a single gas in a volume of the mixture. The partial pressure of dihydrogen is 737.5 mmHg.
What is Dalton's law?
According to Dalton's law, the sum of partial pressure of non-reacting gases gives the total pressure of the system.
Given,
Total pressure = 755.0 mmHg
The partial pressure of water = 17.5 mmHg
The partial pressure of dihydrogen = ?
The partial pressure of dihydrogen is calculated as:
[tex]\begin{aligned}\rm p_{total} &= \rm p_{H_{2}O} + p_{H_{2}}\\\\755.0 &=\rm 17.5 + p_{H_{2}}\\\\&= 737.5 \;\rm mmHg\end{aligned}[/tex]
Therefore, the partial pressure of dihydrogen is 737.5 mmHg.
