Dalton's Law

Problem Set IconCalculatorUsing your knowledge of the Dalton’s Law of Partial Pressures, complete each of the problems below. Remember, to solve each problem, it is best to list the known and unknown variables. Make sure to completely answer each question and to show all of your work.

This activity is available below or in a printable version.

  1. A metal tank contains oxygen, helium, and nitrogen. If the partial pressures of the three gases are 40 atm O2, 20 atm N2, and 25 atm of He, what is the total pressure inside of the tank?
  2. A furnace has a total pressure of 0.99 atm. In the furnace there are two known gases and remaining air. Carbon dioxide is at a partial pressure of 0.05 atm. The partial pressure of hydrogen sulfide is 0.03 atm. What is the partial pressure of the remaining air?
  3. What is the partial pressure of carbon dioxide in a container that holds 5 moles of carbon dioxide, 3 moles of nitrogen, and 1 mole of hydrogen? The container has a total pressure of 1.05 atm.
