2 g of Sodium Hydroxide is dissolved in 25 cm 3of water.
Calculate the amount of heat released given that the temperature
change is 5 oC. Specific heat capacity of water is 4.2Kj/Kg/K. Type in the correct answer.
Mass of water = 25 x 1 = 25g
Specific heat capacity = 4.2
Change in temperature = 5
H = 25 x x 5
