A 10-lane Olympic-sized swimming pool contains #2.5 times 10^6# kg of water. If the water is at 0°C, how many kilojoules of energy of water must be removed to freeze the water in this pool?

We need some more data here....

Explanation:

For (i) the heat capacity of LIQUID water; and (ii) the latent heat of fusion of water (this is an exothermic process in the given example). Anyway these data should have been included in the terms of the question...

Also necessary in the question is the volume of water contained in an Olympic-sized swimming pool...this is #50*mxx20*mxx2*m=2000*m^3#, quite an impressive volume.

I have never lived in a country in the northern hemisphere where I used an outdoor swimming pool in the winter months. The salts they use to purify the water would DEPRESS the melting point. So for someone who swims in say Norway, or Prince George, do they have outdoor swimming pools? If they do not heat them, surely they empty the pools over winter?
