Final answer:
The charge of Vanadium in the compound V(NO3)3 is +3.
Step-by-step explanation:
The charge of Vanadium in the compound V(NO3)3 is +3.
In V(NO3)3, nitrate (NO3) has a charge of -1. Since there are three NO3 groups, the total charge of nitrate is -3. In order for the compound to be neutral, Vanadium (V) must have a charge of +3 to balance out the negative charge of the nitrate groups.
Therefore, the correct answer is d. +3.
