Oxygen gas reacts with powdered aluminum according to the following reaction: 4Al(s) + 3O2(g) = 2Al2O3?

How many liters of O2 gas, measured at 790 mmHg and 25d egrees C, are required to completely react with 2.2 mol of Al?Oxygen gas reacts with powdered aluminum according to the following reaction: 4Al(s) + 3O2(g) = 2Al2O3?
4Al + 3O2 = 2Al2O3


2.2mol x ?





4.0mol 3.0mol





If 1 mol of substance =22.4liters, then








x=(2.2mol Al)(3.0molO2)/(4.0mol Al)





x=1.65mol O2(22.4liters/mol)





x=36.96 Liters of O2 answer
