यदि सामान्य दाढ़ द्रव्यमान (120,g mol\(^{-1}) और (i=1.5) है, तो प्रेक्षित दाढ़ द्रव्यमान क्या होगा\)?
If the normal molar mass is (120,g mol\(^{-1}) and (i=1.5), what is the observed molar mass\)?
Explanation opens after your attempt
B. (80,g mol\(^{-1})\)
Concept
\((i=\frac{M_{\)normal\(}}{M_{\)observed}})। \(/ (i=\frac{M_{\)normal\(}}{M_{\)observed}}).
Why this answer is correct
\((M_{\)observed\(}=\frac{120}{1.5}=80\),g mol^{-1})। \(/ (M_{\)observed\(}=\frac{120}{1.5}=80\),g mol\(^{-1}).\)
Exam Tip
(i>1) होने पर प्रेक्षित दाढ़ द्रव्यमान सामान्य से कम आएगा। / When (i>1), observed molar mass is less than normal molar mass.
