1)Given data:

Number of moles of KOOH produced = ?

Number of moles of LiClO = 5 mol

now we will compare the moles of KOOH and LiClO.

                 LiClO          :          KOOH

                    2              :              1

                   5               :             1/2×5 = 2.5

2.5 moles of KOOH are produced.
