Question

The Mole Fraction of glucose in aqueous solution is 0.2,then molality of solution will be​

Answer 1

The ANSWER is in the attachment

Symbols used:-

• xA = mole fraction of GLUCOSE (solute)
• xB = mole fraction of WATER (universal solvent)
• nA = no. of moles of solute
• nB = no. of moles of solvent
• wB = weight of solute (in grams)
• MwB = molecular mass of H2O
• m = molality= mol/kg
