1.	What is the mass of glucose (C_(6) H_(12) O _(6)) in it one litre solution which is isotonic with 6 gL ^(-1) of urea (NH_(2) CONH_(2)) ?
Answer» Solution :Osmotic PRESSURE of urea solution `(pi_(1)) = CRT` `= (W_(2))/(M _(2) V) RT = (6)/( 60 XX 1) xx RT` Osmotic pressure of glucose solution `(pi _(2)) = (W_(2))/(180 xx 1) xx RT` For isotonic solution, `pi _(1) = pi_(2)` `(6)/(60) RT= (W_(2))/(180) RT implies W_(2) = (6)/(60) xx 180` `W_(2) = 18g`
