Question

a gas mixture 20 degree celcius and 2.9 atm contains .40 moles of h2 .15 mol O2 and .50 mol of n2 assu,ing ideal behavior what is the partial pressure of hydrogen gas h2 in the mixture

Answer 1

Partial pressure of H2 ≈ 1.10661 atm

Step-by-step explanation:

1) Calculate the total moles of the gas mixture:

Total moles = 0.40 moles + 0.15 moles + 0.50 moles

Total moles = 1.05 moles

2) Calculate the mole fraction of H2:

Mole fraction of H2 = 0.40 moles / 1.05 moles

Mole fraction of H2 ≈ 0.3809

3) Use the mole fraction to find the partial pressure of H2:

Partial pressure of H2 = 0.3809 × 2.9 atm

Partial pressure of H2 ≈ 1.10661 atm
