Calculate the moles of SO2 that contains 3.8 moles of O atoms
Olegator [25]
Answer: 1.9 moles SO₂

Explanation:

1) The chemical formula SO₂ shows that for every mol of SO₂ there are 1 mol of S and two moles of O.

2) Then you can state the proportion between the number of moles of SO₂ and O to find how many moles of SO₂:contains 3.8 moles of O.


   1 mol SO₂                         x

-------------------- =   --------------------------

    2 moles O              3.8  moles O


3) Now, you can clear x:

x = 3.8 moles O × 1 mol SO₂ / 2 moles O.

x = 1.9 moles SO₂.
