Question 18 - 2020 (04 Sep Shift 2)
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 $x \times 10^{-3}$ atm. $x$ is ____.
Show Answer
Answer: 167
Solution
$\pi_{\text{Total}} = \frac{0.10}{3} + \frac{0.40}{3} = \frac{0.50}{3} = 167 \times 10^{-3}$ atm.
