Mole fraction of the solute in a 1.00 molal aqueoussolution isA. 0.017

1.	Mole fraction of the solute in a 1.00 molal aqueoussolution isA. 0.0177В.О 0.0344C 1.7700D. 0.1770
Answer» 1.00 molal aqueous solution means that 1 mol of solute is dissolved in 1 Kg of water. Hence,No. Of moles of solute = 1 No. Of moles of water = 1000/18=55.556 MOLE FRACTION OF SOLUTE = No. Of moles of solute/no. Of moles of solute + No. Of moles of solvent MOLE FRACTION = 1/1+55.556 =0.1768[0.0177(approx.)

Answer»

1.00 molal aqueous solution means that 1 mol of solute is dissolved in 1 Kg of water.

Hence,No. Of moles of solute = 1

No. Of moles of water = 1000/18=55.556

MOLE FRACTION OF SOLUTE = No. Of moles of solute/no. Of moles of solute + No. Of moles of solvent

MOLE FRACTION = 1/1+55.556 =0.1768[0.0177(approx.)
