Answer:
Mass of CO2 WILL BE ~ 9.33 g
Explanation:
Moles of O2 = 14/18
Let the mass of CO2 be x
Then moles of CO2 will be = x/12
moles of CO2 = moles of O2
x/12 = 14/16
x = 9.33 grams
We are given the starting amount of Al metal to be used. This will be the starting point of the calculations. We do as follows:
74.00 g ( 1 mol / 26.98 g ) ( 1 mol Al2O3 / 2 mol Al ) ( 101.96 g / 1 mol ) = 139.83 g Al2O3 produced
Hope this answers the question. Have a nice day.
