Ck 12: Gas Mixtures and Molecular Speeds

[Free Registration/Login may be required to access all resource tools.] The following online tutorial helps students use Dalton's Law and mole fraction to calculate the partial pressure of a gas in a mixture. They will learn to calculate the pressure of a gas that has been collected by water displacement in order to determine the volume of the dry gas and define diffusion and effusion. They willl also use Graham's Law to calculate the velocity ratios of two gases based on their molar masses.
