2kclo3 = 3kcl +2o2 how many moles of kclo3 are needed to produce 4.5 moles of kcl?

Coefficients in the chemical equation show ratio of moles of the reactants and products. 
                                    2KCLO3 > 3KCl +2O2
by reaction                   2 mol               3 mol
from problem               x mol              4.5 mol

x=(2*4.5)/3 =9/3 =3 mol  of KClO3  are needed to form 4.5 mol KCl.
