Number 0 Next tl Ext O Previous Give Up & View Solution Check Answer Hint

Explanation / Answer

first, get moles of CO2

2 mol of fuel = 16 mol of CO2

1:8 ratio

then

mol of CO2 = 8*mol of fuel = 8*(4.9*10^2) = 3920 mol of CO2

apply ideal gas law

PV = nRT

V = nRT/P

V = (3920)(0.082)(39+273)/(0.995)

V = 100793.246 Liters
