Which of the following has lowest temperature vapour pressure b1 number of |
|
Answer» Vapour pressure depends on the concentration of non-volatile solute.For Al 2 (SO 4 ) 3 , we need to consider C×i, where C=Concentrationi=VantHoffFactorHence, for Al 2 (SO 4 ) 3 , C×i=0.5×5=2.5For UREA solution, C= 60×10012×1000 =2MFor NaCl solution, C×i=1×2=2For GLUCOSE solution, C= 180×10018×1000 =1MHere, concentration of non-volatile solute is maximum for Al 2 (SO 4 ) 3 . Hence, it will have lowest vapour pressure.Explanation:Mark as brainly please. |
