How many dm cubed of so2 gas at stp can be produced from 2.22 dm cubed of cs2 vapor?

            4.44 dm³ of SO₂

Solution:

The balance chemical equation is as follow,

                              CS₂  +  3 O₂     →      CO₂  +  2 SO₂

According to equation,

           22.4 dm³ (1 mole) CS₂ produces  =  44.8 dm³ (2 mole) of SO₂
So,
                     2.22 dm³ CS₂ will produce  =  X dm³ of SO₂

Solving for X,
                      X  =  (2.22 dm³ × 44.8 dm³) ÷ 22.4 dm³

                      X  =  4.44 dm³ of SO₂
