Question

For polycondensation of a dicarboxylic acid (1.2mol), glycerol (0.4mol), and ethylene glycol(0.6mol)

option a) (1.2 mol + 0.4 mol + 0.6 mol) = 2.2 mol
option b) (1.2 mol × 0.4 mol × 0.6 mol) = 0.288 mol
option c) (1.2 mol - 0.4 mol - 0.6 mol) = 0.2 mol
option d) (1.2 mol ÷ 0.4 mol ÷ 0.6 mol) = 5 mol

Answer 1

To find the total number of moles in a polycondensation reaction, you need to add the moles of each reactant together.

Step-by-step explanation:

The question asks for the total number of moles (mol) in a polycondensation reaction involving a dicarboxylic acid, glycerol, and ethylene glycol. To find the answer, you need to add the moles of each reactant together. Therefore, the correct option is option a) (1.2 mol + 0.4 mol + 0.6 mol).
