Question

n-Butane (C4H10) is burned with stoichiometric amount of oxygen. Determine the mole fraction of carbon dioxide and water in the products. Also, calculate the mole number of carbon dioxide in the products per unit mole of fuel burned.

Answer 1

See details below

Step-by-step explanation:

The balanced reaction equation is given below:

`2C_(4) H_(10)` +
`13O_(2)` →
`8CO_(2)` +
`10H_(2) O`

Mole fraction of CO2 to H20

= 8/10 =
`(4)/(5)`

Mole ratio of C4H10 to CO2 is 2:8 = 1:4

1 mole of n-butane - 38.12 g

4 moles - ?

= 152.48g fuel consumed.
