MOLALITY (m) AND MOLE FRACTION (Xi)
The mole fraction (Xi) of the ith component of a mixture is the number of moles of that component divided by the total number of moles of all components Example 3 Find the mole fraction of both components of a mixture of water (H2O) and ethanol (C2H5OH) that is 50 by mass in each component Source: http://www drcruzan com/Concentration html |

CHAPTER 1 MEASURES OF ATMOSPHERIC COMPOSITION
The mixing ratio CX of a gas X (equivalently called the mole fraction) is defined as the number of moles of X per mole of air It is given in units of mol/mol (abbreviation for moles per mole) or equivalently in units of v/v (volume of gas per volume of air) since the volume occupied by an ideal gas is proportional to the number of molecules |

Solutions
Mole fraction of a component = Number of moles of the component Total number of moles of all the compone nts (2 4) For example in a binary mixture if the number of moles of A and B are nA and nB respectively the mole fraction of A will be xA = + A A B n n n (2 5) For a solution containing i number of components we have: xi = + + + i 1 2 i |
What is mole fraction x x?
Mole fraction X X is the ratio of moles of one substance in a mixture to the total number of moles of all substances. For a mixture of two substances, A A and B B, the mole fractions of each would be written as follows: XA = molA mol A + molB and XB = mol B mol A + molB X A = mol A mol A + mol B and X B = mol B mol A + mol B
What is the mole fraction of a nonelectrolyte?
The mole fraction of a certain nonelectrolytecompound in a solution containing only thatsubstance and water is 0.100. The molecularweight of water is 18.0 g/mol. What addi-tional information is needed to determine themolality of the solution? The density of the solute. The density of the solution. The molecular weight of the compound.
Why is mole fraction used in some calculations?
The mole fraction is used in some calculationsbecause it is massless. The mole divided by the total number of moles of all components of the solution. The sum of the mole fractions of all components is one. gases. that component divided by the total number of moles of all components. (C2H5OH) that is 50% by mass in each component.
How many moles are in a mole?
6.0236 1023 molecules are defined as one mole. i i. The mass fraction of elements is very useful in combustion. Mass of the species changes due to chemical reactions, the mass of the elements is conserved. e is the total number of elements in the system.
