Question

How many moles of CO2 will be obtained when 0.274 moles of C2H5OH is burnt

Answer 1

Dear student,

Balanced equation of combustion of ethanol can be written as:
C₂H₅OH + 3O₂ --> 2CO₂ + 3H₂O
1 mole of C₂H₅OH produces 2 moles of CO₂
so 0.274 mole of C₂H₅OH will produce 0.274 x 2 = 0.548 moles of carbon dioxide.
