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 \[O=\frac{1.21}{16}=0.075\] |
| \[{{V}_{0.03}}\,{{O}_{0.075}}\] |
| \[V{{O}_{2.5}}\Rightarrow {{V}_{2}}{{O}_{5}}\] |
