A) \[48.60\]
B) \[44.2\]
C) \[64.26\]
D) \[69.45\]
Correct Answer: D
Solution :
\[\frac{{{P}_{0}}-{{P}_{S}}}{{{P}_{0}}}=\frac{\omega \times M}{W\times m}\] \[\frac{640-600}{640}\,\,\,\,\frac{2.175\times 78}{m\times 39.08}\] (mol. wt. of \[{{C}_{6}}{{H}_{6}}=78\]) \[m=\frac{2.175\times 78\times 640}{40\times 39.08}\] \[m=69.45\]You need to login to perform this action.
