Calculate mole fraction of ethyl alcohol and water in a solution containing 46 g ethyl and 36g water.

Calculate mole fraction of ethyl alcohol and water in a solution containing 46 g ethyl and 36g water.

Calculate the mole fraction of ethanol if 9.2 g of it is mixed with 1.8 g water.

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")
