V(с6н6) = (0,88 (г/см) *1000 (см3)) / 78 (г/моль) = 11,282 моль 2с6н6 + 15о2 > 12со2 + 6н2о на 2 моль бензола - 15 моль кислорода => на 11,282 моль бензола - 84,615 моль кислорода. в воздухе условно 1/5 часть кислорода, потому: v (воздуха) = 84,615 моль * 22,4 (л/моль) * 5 = 9476,88 л. (т. е. почти 1м3)
