Question

Calculate the moles of co2 obtained when 0.274 mole of C2H5OH is burnt in air.

Answer 1

Answer:

C2H5OH+3O2-------->2CO2+2H2O

1 mole. 2 mole

1 mole of C2H5OH produces 2 mole of CO2

therefore 0.274 mole of C2H5OH produces

=2/1*0.274

=0.548 mole

Thus 0.548 mole of CO2 is obtained from 0.274 of C2H5OH.

Answer 2

Answer:

0.548 moles of carbon dioxide are obtained when 0.274 moles of C₂H₅OH are burnt in the air.

Explanation:

The reaction of ethanol with oxygen is carried out as follows,

$\mathrm{C_2H_5OH+O_2\rightarrow 2CO_2+3H_2O}$      (1)

Where,

C₂H₅OH=ethanol

O₂=oxygen

CO₂=carbon dioxide

H₂O=water

From reaction (1) we can interpret that one mole of ethanol gives two moles of carbon dioxide.

So, when 0.274 moles of ethanol i.e.C₂H₅OH gives,

= 0.274×2=0.548 moles of carbon dioxide i.e.CO₂.
