2 C2H6(g) +7 O2(g) = 4 CO2(g) + 6 H2O(g)
1. Calculate the volume in liters of CO2 at STP, that could be produced from 7.25 g C2H6.
2. Calculate the volume of O2 at 100oC and 1.25 atm, that would react with 7.52g of C2H6
1. M(C2H6) = 30.07 g/mol
n(C2H6)
According to the reaction equation
n(CO2) = 2n(C2H6)
At STP one mole of any gas occupies 22.4 L.
V(CO2)
2. n(C2H6)
According to the reaction equation
n(O2) n(C2H6)
Ideal gas law:
R = 0.08206 L×atm/mol×K
