Suppose, in an experiment to determine the amount of sodium hypochlorite in bleach, you titrated a 27.59mL sample of 0.0100M KIO3 with a solution of Na2S2O3 of unknown concentration. The endpoint was observed to occur at 17.46 mL. How many moles of KIO3 were titrated?

can you attach the

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

i think its 100.

hope this !
