यदि \(K_b=0.52,K,kg,mol^{-1}\), \(w_2=2,g\), \(w_1=100,g\) और \(\Delta T_b=0.104,K\) है, तो (M) क्या होगा?
If \(K_b=0.52,K,kg,mol^{-1}\), \(w_2=2,g\), \(w_1=100,g\), and \(\Delta T_b=0.104,K\), what is (M)?
Explanation opens after your attempt
B. \(100,g,mol^{-1}\)
Concept
Take \(M=\frac{K_bw_2\times1000}{\Delta T_bw_1}\).
Why this answer is correct
\(M=\frac{0.52\times2\times1000}{0.104\times100}=100,g,mol^{-1}\).
Exam Tip
In boiling point method also, use (1000) when solvent mass is in grams. चरण 1: सूत्र \(M=\frac{K_bw_2\times1000}{\Delta T_bw_1}\) लें। चरण 2: \(M=\frac{0.52\times2\times1000}{0.104\times100}=100,g,mol^{-1}\)। चरण 3: क्वथनांक विधि में भी विलायक का द्रव्यमान ग्राम में हो तो (1000) प्रयोग करें।
