Calculate the mass of vanadium(v) oxide (v2o5) that contains a million (1.0 *10^6) vanadium atoms. be sure your answer has a unit symbol if necessary, and round it to 3 significant digits.

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

Explanation:

It is known that molar mass of is 181.88 g/mol.

We will calculate the number of vanadium atoms present in 1 mole of as follows.

                  atoms

                  = atoms

Therefore, mass of which contains atoms of vanadium = Molar mass of = 181.88 g/mol.

Hence, we will calculate the mass of that contains vanadium atoms as follows.

              =

Thus, we can conclude that mass of in given situation is g/mol.
