Answer : The amount of heat released is, -1602.36 KJ

Explanation : Given,

Moles of NaOH = 3.600 mole

Molar heat of solution of NaOH = -445.1 KJ/mole

Now we have to calculate the amount of heat released.

As, 1 mole of NaOH is dissolved in water then heat released = - 445.1 KJ

So, 3.600 mole of NaOH is dissolved in water then heat released =
-445.1* 3.600=-1602.36KJ

Therefore, the amount of heat released is, -1602.36 KJ
