Text Solution

Verified by Experts

The correct Answer is:
a,c
(a,c) Osmotic pressure `(pi)=iCRT`
`C_((Urea))=6g/100mL=60g/L=((60g))/((60"g mol"^(-1)))=1M`
`ppi_((urea))=iCRT=RT(i=1)`
`pi_((glucose))=18g/100mL=180g/L=((180g))/((180"g mol"^(-1)))=1M`
`pi_("glucose")=iCRT=RT.I(i=1)`
`(b)pi(BaCI_(2))=iCRT=(3)xx(0.5)RT=1.5RT` ltbtgt `(c) pi_(("sucrose"))=CRT=(1)RT=RT`
`(d)pi_(("acetic acid"))=CRT=iCRT=2xx1RT=2RT`
Thus (a) and (c) are isotonic with 6% solution of urea.
