JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry

\(500\,g\,0.25\,molar\) જલીય દ્રાવણ અને \(250\,mL 0.25\,molar\) જલીય દ્રાવણ બનાવવા માટે ઈથિલિન ગ્લાયકોલ \(\left( C _2 H _6 O _2\right.\), મોલર દળ = \(\left.62\,g / mol \right)\) નો કેટલો દળ ગુણોત્તર જરૂરી છે ?

  1. A \(1: 1\)
  2. B \(3: 1\)
  3. C \(2: 1\)
  4. D \(1: 2\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(2: 1\)

Step-by-step Solution

Detailed explanation

Assume : Mass of solvent \(\approx\) Mass of solution Case \(I:-\) \(0.25=\frac{ W _1}{62} \times \frac{1000}{500}\) Case \(II:-\) \(0.25=\frac{ W _2}{62} \times \frac{1000}{250}\) \(\frac{ W _1}{ W _2}=\frac{2}{1}\)
