A) \[{{V}_{2}}{{O}_{3}}\]
B) \[VO\]
C) \[{{V}_{2}}{{O}_{5}}\]
D) \[{{V}_{2}}{{O}_{7}}\]
Correct Answer: C
Solution :
[c] Mass of oxide = Mass of metal + Mass of oxygen |
\[2.74=1.53+{{W}_{Oxygen}}\Rightarrow {{W}_{Oxygen}}=1.21g\] |
Moles of \[V=\frac{1.53}{51}=0.03\] |
Moles of \[O=\frac{1.21}{16}=0.075\] |
\[{{V}_{0.03}}\,{{O}_{0.075}}\] |
\[V{{O}_{2.5}}\Rightarrow {{V}_{2}}{{O}_{5}}\] |
