If x molal solution of a compound |
| Answer» MOL fraction of SOLUTE=0.2hence mol fraction of benzene=1-0.2=0.8it MEANS that 0.8 mol of benzene contains 0.2 mol of solute..................⇒0.8*78G of benzene contains 0.2 moles of solute⇒ 62.4g.................................0.2mol...............⇒1g......................................(0.2/62.4)mol.......HENCE 1000g of benzene would contain (1000/62.4)*0.2 mol of solute=3.2=molality of solute=xPLEASE FOLLOW ME | |
