PT: \(\left(C_{17}H_{35}COO\right)_3C_3H_5+3NaOH\underrightarrow{t^o}3C_{17}H_{35}COONa+C_3H_5\left(OH\right)_3\)
Ta có: \(n_{\left(C_{17}H_{35}COO\right)_3C_3H_5}=\dfrac{4500}{890}=\dfrac{450}{89}\left(mol\right)\)
Theo PT: \(n_{C_{17}H_{35}COONa}=3n_{\left(C_{17}H_{35}COO\right)_3C_3H_5}=\dfrac{1350}{89}\left(mol\right)\)
\(\Rightarrow m_{C_{17}H_{35}COONa}=\dfrac{1350}{89}.306\approx4641,6\left(g\right)\)
\(\Rightarrow m_{xp}=\dfrac{4641,6}{60\%}=7736\left(g\right)\)
