Answer:

Number of moles = 3.82 mol

Explanation:

Given data:

Number of moles of CO₂ = ?

Mass of CO₂ = 168.2 g

Solution:

Number of moles = mass/molar mass

Molar mass of CO₂ = 44 g/mol

By putting values,

Number of moles = 168.2 g/ 44 g/mol

Number of moles = 3.82 mol

In the process of oxidizing i− to i2, so42− is reduced to so2. how many moles of so2 are produced in the formation of one mole o
mafiozo [28]
The balance chemical equation is follow,

                    2 I⁻  + SO₄²⁻  +  4 H⁺    →    I₂  +  SO₂  +  2 H₂O

According to this reaction, 2 moles of I⁻ reacts with 1 mole of SO₄²⁻ to produce 1 mole of I₂ and 1 mole of SO₂.

Result:
          So with the formation of 1 mole of I₂, 1 mole of SO₂ is produced.
