A) \[5.96\]
B) \[5.96\times {{10}^{-2}}\]
C) \[5.96\times {{10}^{-1}}\]
D) \[5.96\times {{10}^{-3}}\]
Correct Answer: D
Solution :
[d] \[5.96\times {{10}^{-3}}\] Molar volume from pyknometric density, \[=\frac{M}{2.165\times {{10}^{3}}}{{m}^{3}}\] Molar volume fro x -ray density \[=\frac{M}{2.178\times {{10}^{3}}}{{m}^{3}}\] \[\therefore \]volume occupied \[=\frac{M}{{{10}^{3}}}\left( \frac{1}{2.165}-\frac{1}{2.178} \right){{m}^{3}}\] \[=\frac{0.013M\times {{10}^{-3}}}{2.165\times 2.178}\] \[\therefore \]fraction occupied \[=\frac{(0.013\times {{10}^{3}})}{2.165\times 2.178}\div \frac{M\times {{10}^{-3}}}{2.165}\] \[=5.96\times {{10}^{-3}}\]You need to login to perform this action.
