Question

72 gram of c5h12 combution
what will be mass of Co2 and H2o​

Answer 1

combustion reaction of C5H12

C5H12 + 8O2 = 5CO2 + 6H2O

Molecular mass of C5H12= 72g

No of moles of C5H12 =72/72=1 mole

For 1 mole of C5H12 5 mole of CO2 is given out

molecular mass of CO2=44g

mass=44×5=220g

For 1 mole of C5H12 6 mole of H2O is obtained

molecular mass of H2O =18g

mass=18×6=108g.,...
