m(CH3-CH(CH3)-CH2-CH2-CH3) = 280 g
V(CO2)-?
2CH3-CH(CH3)-CH2-CH2-CH3 + 19O2-->12CO2+14H2O
M(CH3-CH(CH3)-CH2-CH2-CH3) = 86 g/mol
n(CH3-CH(CH3)-CH2-CH2-CH3) = m/M = 280 / 86 = 3.26 mol
2n(CH3-CH(CH3)-CH2-CH2-CH3) =12n(СO2)
n(O2) = 12*3.26 / 2 = 19.56 mol
V(O2) = n*Vm = 19.56 * 22.4 = 438.144 L
ответ 438.144 L
