Answer to Question #156037 in General Chemistry for Hamzah Algaradi

Question

If 400 molecules of C 23 H 32 (g) combust with oxygen , O 2 (g) , how many molecules of carbon dioxide gas, CO 2 (g) ,will be produced ?

Answer 1

The balanced equation for the reaction is;

C₂₃H₃₂ + 31O₂ $\implies$ 23CO₂ + 16H₂O

From the balanced equation;

1 molecule of C23H32 gives 23 molecules of CO2,

400 molecules will give?

$=\dfrac{400x23}{1} = 9200 molecules$
