fiasKO [112]

Answer:

6 moles of SO₃ formed.

Explanation:

Given data:

Number of moles of SO₃ formed = ?

Number of moles of oxygen react = 3 mol

Solution:

Chemical equation;

2SO₂+ O₂      →   2SO₃

now we will compare the moles of oxygen and sulfur trioxide.

                             O₂            :            SO₃

                               1             :             2

                               3            :           2/1×3 = 6 moles

Thus, six moles of SO₃ will formed.
