\(यदि (K_b=0.52\),K kg mol\(^{-1}), (m=0.50\),mol kg\(^{-1}) और देखा गया उबालांक उन्नयन (0.39\),K) है तो (i) का मान क्या होगा?
\(If (K_b=0.52\),K kg mol\(^{-1}), (m=0.50\),mol kg\(^{-1}), and the observed boiling point elevation is (0.39\),K), what is the value of (i)?

C. (1.50)
Concept
\(सामान्य उन्नयन (\Delta T_b=K_bm=0.52\times0.50=0.26\),K) है। \(/ Normal elevation is (\Delta T_b=K_bm=0.52\times0.50=0.26\),K).
Why this answer is correct
\(i=\frac{0.39}{0.26}=1.50\)। / \(i=\frac{0.39}{0.26}=1.50\).
Exam Tip
(i>1) हो तो कणों की संख्या बढ़ी है। / If (i>1), the number of particles has increased.
