Question

If 4.36 moles of C5H12 reacts with excess O2, how many moles of CO2 will be produced in the following combustion reaction?

C5H12 + 8O2 -----> 6H2O + 5CO2

Answer 1

`21.80` moles

Explanation:

`C_5H_12+8O_2 rarr 6H_2O + 5CO_2`

From the equation, we see that 1 mole of `C_5H_12` reacts with excess of `O_2` to produce `5` moles of `CO_2.`

So, `4.36` moles of `C_5H_12` will react with excess `O_2` to produce
`(4.36*5)` moles`=21.80` moles.

That's it .
