Question

Calculate the enthalpy change for the hydrolysis of 2 moles of sucrose (C12H22O11) given that the enthalpy change of hydrolysis for 1 mole of sucrose is -564 kJ/mol.

Answer 1

To calculate the enthalpy change for the hydrolysis of 2 moles of sucrose, you simply multiply the enthalpy change for 1 mole of sucrose by the number of moles.Enthalpy change for 1 mole of sucrose = -564 kJ/molNumber of moles = 2Enthalpy change for 2 moles of sucrose =  -564 kJ/mol   2 = -1128 kJ
