Question 6

What is Dalton's Law of Partial Pressures?

Accepted Answer

Total pressure of a gas mixture equals the sum of partial pressures of each gas

Answer

Each gas exerts pressure based on all molecules present

Answer

Pressure of a gas is inversely proportional to its molar mass

Answer

Gas pressure depends only on temperature
