Answer:

2.25 atm

Explanation:

Given data

Pressure of N₂: 321 kPa

Pressure of O₂: 74.0 psi

Pressure of H₂: ?

Total pressure: 10.46 atm

Step 1: Convert the pressure of nitrogen to atm

We will use the relationship 1 atm = 101.325 kPa.

$321kPa \times \frac{1atm}{101.325kPa} = 3.17 atm$

Step 2: Convert the pressure of oxygen to atm

We will use the relationship 1 atm = 14.6959 psi.

$74.0psi \times \frac{1atm}{14.6959psi} =5.04atm$

Step 3: Calculate the partial pressure of hydrogen

The total pressure is the sum of the partial pressures.

P = pN₂ + pO₂ + pH₂

pH₂ = P - pN₂ - pO₂

pH₂ = 10.46 atm - 3.17 atm - 5.04 atm

pH₂ = 2.25 atm
