Question

4. A mixture of hydrogen and oxygen gases has a total pressure of 5.50 atm. What is the

partial pressure of the hydrogen if the P102) = 1250 mm Hg?

Answer 1

Answer: 3.86atm is the partial pressure for hydrogen.

Step-by-step explanation:

1 atmosphere = 760 mm Hg

So total pressure for oxygen and hydrogen is 5.50atm

changing The partial pressure of oxygen from mmHg to atm we have

1250/760 atm = 1.645atm

----The total pressure of a mixture of gases is the sum of the partial pressures of the gases that make it up.

Dalton's Partial Pressure = P total =p 1 +p 2 +p 3 +...

P₅.₅₀=pO₂(1.645atm) +pH₂

So the partial pressure of Hydrogen is 5.50- 1.645= 3.855= 3.86atm.
