Given information

The percentage by mass of vanadium in its first oxide is  

The percentage by mass of vanadium in its second oxide is  

The percentage by mass of vanadium in its third oxide is  

The percentage by mass of vanadium in its fourth oxide is  

 

Step-by-step explanation

Step 1.

The percentage by mass of vanadium in its first oxide is  That means in  of its oxide, vanadium contains  and oxygen contains In general the mass of vanadium in its first oxide is is  and the mass of oxygen in its first oxide is .

The molar mass of vanadium is  

The molar mass of oxygen  is  

The number of moles of vanadium   in its first oxide is calculated by the formula,

                     ....(1)

Where,

  •   is mass of vanadium in its first oxide.

  •   is molar mass of vanadium.

Substitute the values of  and in equation (1),

 

         

The number of moles of oxygen  in the first oxide of vanadium is calculated by the formula,

                       .....(2)

Where,

  •   is mass of oxygen in the first oxide of vanadium.

  •   is molar mass of vanadium.

Substitute the values of  and   in equation (2),

 

       

The ratio of moles of vanadium to oxygen is,

             

 

Simplify the above values,

     

         

   

The number of moles of both vanadium and oxygen are equal. Therefore, the formula of first oxide of vanadium is . The name of this oxide is vanadium monoxide.
