Mass and Mole Fractions
Apply the basic concepts of non-reacting mixtures in general and air-vapour mixtures in particular system.
Perform calculations to determine the mole fractions of gases within and gas mixture and relate mole fraction to the partial pressure of a gas within a gas mixture.
Mass fraction, \(m_f\): the ratio of the mass of a component to the mass of the mixture
Mole fraction, y: the ratio of the mole number of a component to the mole number of the mixture.
What is the mole fraction of Ascorbic acid, C$_6$H$_8$O$_6$, in a solution containing 80.5 g of Ascorbic acid and 210 g of water?
A mixture of 1.00 mole of O$_2$ and an unknown number of moles of N$_2$ is maintained under standard conditions. If 3.00 moles of O$_2$ are added to the mixture, maintaining the same conditions, the volume doubles. How many moles of N$_2$ are present?
