Question
The osmotic pressure of a solution of NaCl is
0.10 atm and that of a glucose solution is
0.20 atm. The osmotic pressure of a solution
formed by mixing 1 L of the sodium chloride
solution with 2 L of
the glucose solution is x 10–3 atm. x is _____. (nearest integer)
the glucose solution is x 10–3 atm. x is _____. (nearest integer)

Show full solutionCorrect answer: 167
Correct answer
167
Step-by-step explanation
For NaCl : 1 = 0.1 atm, v1 = 1 L
For Glucose: 2 = 0.2 atm, v2 = 2 L
mix =
=
= =
= 167 10-3 atm
For Glucose: 2 = 0.2 atm, v2 = 2 L
mix =
=
= =
= 167 10-3 atm
