Which oxide of vanadium contains the greatest mass percent of the metal? vo2v2o3vov2o5

Answer : The oxide of vanadium contains the greatest mass percent of the metal is,

Explanation: Given,

Molar mass of vanadium = 50.9 g/mol

Now we have to calculate the mass percent of metal in the following compounds.

For compound :

Molar mass of = 82.9 g/mole

Now put all the given values in this formula, we get:

Therefore, the mass percent of vanadium metal is 61.4 %

For compound :

Molar mass of = 149.8 g/mole

Now put all the given values in this formula, we get:

Therefore, the mass percent of vanadium metal is 33.9 %

For compound :

Molar mass of = 66.9 g/mole

Now put all the given values in this formula, we get:

Therefore, the mass percent of vanadium metal is 76.1 %

For compound :

Molar mass of = 181.8 g/mole

Now put all the given values in this formula, we get:

Therefore, the mass percent of vanadium metal is 27.9 %

Hence, the oxide of vanadium contains the greatest mass percent of the metal is,
