Answer : The mass of vanadium(V) oxide will be 
Explanation : Given,
Number of atoms of 
= 
Molar mass of = 181.88 g/mole
In , there are 2 atoms of vanadium and 5 atoms of oxygen.
First we have to determine the moles of .
As, 
number of vanadium atom present in 1 moles of
So, number of vanadium atom present in 
moles of
Now we have to determine the mass of .
Therefore, the mass of vanadium(V) oxide will be
