Question

How many moles of CO2 will be obtained when 0.27u mole of C2H5OH is burnt

Answer 1

Answer:

0.135 moles of CO2

Explanation:

The balanced reaction of combustion of ethanol is

C2H5OH + 3O2 ⇒ 2CO2 + 3H2O

From the equation it is clear that 1 mole of ethanol gives 2 moles of CO2 on burning.

Thus 0.27 moles of ethanol will give 0.27/2 = 0.135 mol of CO2.
