Question

Calculate the number of moles of methane required to produce 33 g of carbon dioxide gas on its complete combustion.
(A) 0.15 moles
(B) 0.50 moles
(C) 0.75 moles
(D) 0.95 moles

16g of CH4 gives 44g of CO2

? g of CH4 gives 33g of CO2

12g of CH4 gives 33g of CO2

no, of moles = weight/ molecular weight

=12g/16g= 0.75moles
