A) 2
B) 1
C) 4
D) None of these
Correct Answer: D
Solution :
\[\frac{{{P}^{o}}-{{P}_{s}}}{{{P}_{s}}}=\frac{n}{N}=\frac{n\,\,\times \,\,M}{W}=\frac{n\,\,\times \,\,M\,\,\times \,\,1000}{W\,\,\times \,\,1000}\] |
\[=\frac{molality\times M}{1000}\] |
\[Thus=\frac{100-95}{95}=\frac{m\times 18}{1000}\] |
\[\therefore \,\,\,m=2.92\] |
