The replacing of sodium hydroxide with potassium hydroxide
(KOH) to the reaction will least affect the organic product that forms.
Potassium hydroxide is an
inorganic compound with the formula KOH, and is commonly called caustic potash. Along with sodium hydroxide, this colorless
solid is a prototypical strong base.
Maybe it's [Acid] and [H+ ions]
The heat absorbed by the water that evaporates from the body is the so called latent vaporization heat of water.
The standard latent vaporization heat of water is 2,264.705 kJ / kg.
So, you just have to divide 125 kJ / 2,264.705 kJ/kg = 0.0552 kg = 55.2 g
Answer: 55.2 g
