A) \[18\,\,c{{m}^{3}}\]
B) \[22400\,\,c{{m}^{3}}\]
C) \[6.02\times {{10}^{-23}}\,\,c{{m}^{3}}\]
D) \[3.0\times {{10}^{-23}}\,\,c{{m}^{3}}\]
Correct Answer: D
Solution :
\[d=\frac{M}{V}\]; \[1=\frac{M}{V}\] or M = V; 18gm = 18ml \[6\times {{10}^{23}}\]molecule of water has volume =18cc 1 molecule of water has volume \[=\frac{18}{6\times {{10}^{23}}}\] \[=3\times {{10}^{-23}}c{{m}^{3}}\].
