Ans: 0.709 moles glycerin
The given reaction is:
14KMnO4 + 4C3H5(OH)3 → 7K2CO3 + 7Mn2O3 + 5CO2 + 16H2O
a) Based on the reaction stoichiometry:
5 moles of CO2 requires 14 moles of KMnO4
Therefore, 0.886 moles of CO2 would correspond to:
= 0.886 moles CO2 * 14 moles KMnO4/5 moles CO2
= 2.48 moles
b) Again from the reaction stoichiometry:
5 moles of CO2 requires 4 moles of glycerin
therefore, 0.886 moles of CO2 would consume:
= 0.886 moles CO2 * 4 moles glycerin/5 moles CO2
= 0.709 moles
