m(изв) = 130 g
W(CaCO3) =90%
m(ppa HCL) = 365 g
W(HCL) = 20%
V(CO2)-?
m(CaCO3) = 130*90% / 100% = 117 g
m(HCL) = 365 * 20% / 100% = 73 g
M(CaCO3) = 100 g/mol
n(CaCO3) = m/M = 117 / 100 = 1.17 mol
M(HCL) = 36.5 g/mol
n(HCL) = m/M = 73 / 36.5 = 2 mol
n(CaCO3) < n(HCL)
CaCO3+2HCL-->CaCL2+CO2+H2O
n(CaCO3) = n(CO2) = 1.17 mol
V(CO2) = n(CO2)*Vm = 1.17 * 22.4 = 26.208 L
