Answer: 69.7 g
In general:
Where
Mp : Mass of Product (CO2)
Wp : Atomic-Weight of Product = 44.009 g/mole
Np : Stocimetric Number of Product (ie. moles in the equation) = 16
Mr : Mass of Reactant (C8H18) = 22.6 g
Wr : Atomic-Weight of Reactant = 114.23 g/mole
Nr : Stocimetric Number of Reactant = 2
Mp = 69.656 g
Code: Select all
Mp = (Np * Wp * Mr) / (Nr * Wr)
Where
Mp : Mass of Product (CO2)
Wp : Atomic-Weight of Product = 44.009 g/mole
Np : Stocimetric Number of Product (ie. moles in the equation) = 16
Mr : Mass of Reactant (C8H18) = 22.6 g
Wr : Atomic-Weight of Reactant = 114.23 g/mole
Nr : Stocimetric Number of Reactant = 2
Mp = 69.656 g
