C7H12 reacts with O2 to produce CO2 and H2O. Suppose 348 g of CO2 are produced in this reaction. What mass of O2 reacted?
As per the chemical equation for the combustion of
eleven moles of Oxygen is needed and 7 moles of Carbon dioxide is released.
In terms of mass, 11 moles of Oxygen, ( 11 x 32 g = 352 g ) of Oxygen is needed to produce , 7 moles of Carbon Dioxide,
( 7 x 44 g = 308 g ) of Carbon dioxide is produced.
To produce 348 g of Carbon dioxide, we will need ,
= 352 g of
= 397.7 g of
