Answer:
The heat of the solution of salt is 1.66.11 J/g.
Explanation:
Mass of the water = m = 46.52 g
Initial temperature of the water =
Final temperature of the water =
The specific heat of water, c = 4.180 J/gºC
Heat associated with water on dissolving salt: q
Negative sign means that heat was lost by water on an addition of a salt.
Heat released on dissolving of salt = -Q = 748.65 J
Mass of salt added = 4.5069 g
Heat of the solution of salt :
=
The heat of the solution of salt is 1.66.11 J/g.
