This  is  because  absorbed  heat  energy or  released  by  water  is dependent on  mass of  water.
q=mc delta  T
where  q is  the amount  of  energy  required,   m  is  the  mass , C  is   the  specific  heat  capacity  and  delta  T is change  in  temperature.

Answer:

2.5 moles of KOOH are produced.

Explanation:

1)Given data:

Number of moles of KOOH produced = ?

Number of moles of LiClO = 5 mol

Solution:

Chemical equation:

2LiClO +  KHSO₄     →      Li₂SO₄ + Cl₂ + KOOH

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.
