How many moles of SO2 are required to produce 0.45 mole CS2?

The answer to your question is 0.9 moles of SO₂  

Explanation:

Data

moles of SO₂ = ?

moles of CS₂ = 0.45

Balanced chemical reaction

           2SO₂  +  CO₂  ⇒   CS₂  +  3O₂

Use proportions and cross multiplication to solve this problem

                    2 moles of SO₂ 1 mol of CS₂

                     x moles of SO₂ 0.45 moles of CS₂

                     x = (2 x 0.45) / 1

                   x = 0.9 moles of SO₂        

i wish i could but this one is weird give me abc and i can solve it.
