Answer to Question #128669 in Physical Chemistry for Muhammad Nabeel

Question

how mole fraction is to use distinguished between solute and solvent in a solution when contain equal amount of solute and solvent

Answer 1

 solute and solvent in a solution when contain equal amount of solute and solvent .

then Both Have Equal Mass .

let mass of solute and solvent both have " W " .

Molar Mass Of Solute And Solvent = M" AND M"" Respectevely .

 Moles of solute = W / M".

Moles of sovent = W / M"".

Moles of solution = W/ M" + W / M"".

SO ,MOLE FRACTION OF SOLUTE = MOLES OF SOLUTE / MOLESOF SOLUTION .

= W / M" / W/ M" + W / M"".

SO , MOLE FRACTION OF SOLVENT = MOLES OF SOLVENT / MOLESOF SOLUTION .

= W / M"" / W/ M" + W / M"".
