Expert Solution
Step 1

A mole of a substance can be defined as the mass of that substance that contains the same number of fundamental units as atoms in 12.0 g of 12C.

These fundamental units can be atoms, molecules, or formula units that depends on the substance.  1 mol of any atom, molecule or formula unit contains 6.02 x 1023 atoms, molecules or formula units.

Step 2

Given:

Number of Ba atoms = 42 

 

Number of O2 molecules = 13 molecules

Calculate moles of Ba and O2:

Step 3

According to balance chemical equation: 

2 mole Ba = 2 moles BaO 

1 mole O2  = 2 moles BaO
