Question

How many atoms of Oxygen (O) are there in the products of the following equation:

Answer 1

Answer:

We can say, there are 4 mol of oxygen with (4 . NA) = 2.40ₓ10²⁴ atoms

Or just, 4 atoms oxygen.

Explanation:

CH₄  +  2O₂  →  CO₂  +  2H₂O

1 mol of methane reacts with 2 mol of oxygen to produce 1 mol of carbon dioxide and 2 mol of water.

We count in 1 mol of CO₂, we have 2 mol of oxygen

In 2 mol of water, we have 2 mol of oxygen.

We can say, there are 4 mol of oxygen with (4 . NA) = 2.40ₓ10²⁴ atoms

Or just, 4 atoms oxygen.
