Answer:
154 kg
Explanation:
Step 1: Define conversion
1 kg = 2.20 lbs
Step 2: Use Dimensional Analysis
= 153.636 kg
Step 3: Simplify
We are give 3 sig figs.
153.636 kg ≈ 154 kg

Considering the Dalton's partial pressure, the total pressure in the mixture of gases is 1.371 atm.
The pressure exerted by a particular gas in a mixture is known as its partial pressure.
So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:
=
where n is the amount of gases in the mixture.
Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture. So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:
=
In this case, the partial pressure of gas H₂ can be expressed as:
=
You know:
= 0.48 atm
= 0.35
Replacing in the definition of partial pressure of gas H₂:
Solving:
=
= 1.371 atm
In summary, the total pressure in the mixture of gases is 1.371 atm.
