A) 307.8 mL
B) 168.7 mL
C) 323.9 mL
D) 253.3 mL
Correct Answer: C
Solution :
Equal number of moles contain equal number of molecules. \[\frac{wt.\,of\,{{C}_{2}}{{H}_{5}}OH}{mol.\,wt.\,of\,{{C}_{2}}{{H}_{5}}OH}=\frac{wt.\,of\,{{H}_{2}}O}{mol.\,wt.\,of\,{{H}_{2}}O}\] \[\frac{0.789\times volume\,\,of\,{{C}_{2}}{{H}_{5}}OH}{46}=\frac{1.0\times 100}{18}\] Volume of \[{{C}_{2}}{{H}_{5}}OH=\frac{100}{8}\times \frac{46}{0.789}\] \[=323.9\,\,mL\]You need to login to perform this action.
