Define mole fraction.

Define the mole fractin of a substance in solution.

What is false for mole fraction

Define (i) Mole fraction (ii) Van't Hoff factor.

A chemist prepared a solution by adding by 230 g of pure ethanol (C_(2)H_(5)OH) to 144 g of water. Calculate the mole fractions of these two components. The molar masses of ethanol and water are 64 g and 18 g , respectively. Strategy: To calculate the mole fractions, we must find the number of moles of ethanol and of water. To find the moles, we must divide the given mass by the respective molar mass. In a two-component system made up of A and B molecules, the mole fraction of a component of a solution, say, component A is written chi_(A) and is defined as Mole fraction of component A= chi_(A) =("moles of A")/("sum of moles of A and B")

illustration, use OF pressure instead OF moles,use OF volume fraction & mole fraction

If mole fraction of sodium chloride in sodium chloride aqueous solution is 0.35, then mole fraction of water in the solution is

If the mole fraction of a solute in a binary solution is 0.3 , what could be the mole fraction of the solvent in the solution?

The sum of the mole fraction of the components of a solution is
