A) 60
B) 46.17
C) 120
D) 90
E) 92.34
Correct Answer: A
Solution :
Solutions having same osmotic pressure are called isotonic solutions. The osmotic pressure is given as: \[\because \] \[\pi =\frac{{{w}_{B}}RT}{V{{M}_{B}}}\] \[\pi \](cane sugar) = \[\pi \] (unknown solute) \[\frac{5.12}{3.42}=\frac{0.9}{M}\] \[M=\frac{342\times 0.9}{5.12}\] \[=60\]You need to login to perform this action.
