m(C3H7OH) = 60 kg = 60000 g
η(C3H6) -?
-----------------------------------
V практ(C3H6)-?
C3H7OH-->C3H6+H2O
M(C3H7OH) = 60 g/mol
n(C3H7OH) = m/M = 60000 / 60 = 10000 mol
n(C3H7OH) = n(C3H6) = 10000mol
V теор (C3H6) = n*Vm = 10000 * 22.4 = 224000 L
V практ(C3H6) = V(C3H6) * η / 100% = 224000 * 70% / 100% = 156800 L
ответ 156800 л
