Unit 1 review option-Dalton's Law

Since all 3 gases are in the same container, we know with absolute certainty that all 3 gases have the exact same what?

• Pressure

• Temperature

• Volume

• None of the above

If you add up the pressure of the three gases in their individual containers, they will equal the original total pressure of the three gases in the same container.

• True

• False

Which one would be the correct equation (no numbers) to solve this problem using Dalton's Law?

• Total Pressure = P_H + P_He + P_Ne + P_Ar

• Total Pressure = P_H - P_He - P_Ne - P_Ar

• Total Pressure = P_H x P_He  x  P_Ne x  P_Ar

• Total Pressure = P_H / P_He  /  P_Ne /  P_Ar

Set up this problem using the equation for Dalton's Law of partial pressures.

• P_H = 93.6 + 15.4 + 25.7 + 35.6

• 93.6 = P_H + 15.4 + 25.7 + 35.6

• P_H = 15.4 + 25.7 + 35.6 - 93.6

• None of the above

What is the correct answer to the problem?

• 16.9 kPa

• 32.3 kPa

• 7.9 kPa

• None of the above
