What mass of co was used up in the reaction with an excess of oxygen gas if 24.7 g of carbon dioxide is formed
sleet_krkn [62]
Balance Chemical Equation of this reaction is,

                                      2 CO  +  O₂   →   2CO₂

Acc. to this reaction,

88 g (2 mole) of CO₂ was produced when  =  56 g (2 mole)of CO was reacted
So, 
24.7 g of CO₂ will be produced by reacting =  X g of CO

Solving for X,

                                    X  =  (56 g × 24.7 g) ÷ 88 g

                                    X  =  2.26 g ÷ 88 g

                                    X  =  0.0257 g of CO

Result:
           
0.0257 g of CO is required to be reacted with excess of O₂ to produce 24.7 g of CO₂.
