A mixture of h2 and water vapor is present in a closed vessel at 20.00°c. the total pressure of the system is 755.0 mmhg. the partial pressure of the water vapor 17.50 mmhg. what is the partial pressure of h2? type in your answer using the correct number of significant figures. mmhg

Sagot :

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.
