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.......... (nearest integer)
- A \(150\)
- B \(167\)
- C \(160\)
- D \(159\)
Answer & Solution
Correct Answer
(B) \(167\)
Step-by-step Solution
Detailed explanation
Osmotic pressure \(=\pi= i \times C \times RT\) For \(NaCl i =2\) so \(\pi_{ NaCl }= i \times C _{ NaCl } \times RT \quad C _{ NaCl }=\) conc. of \(NaCl\) \(0.1=2 \times C _{ NaCl } \times RT\) \(C_{ NaCl }=\frac{0.05}{ RT } \quad C_{\text {glucose }}=\) conc. of glucose For…
