Answer: You could put the frozen block of ice on the stove and let it melt and eventually boil out leaving the salt behind
Explanation:
Answer:
Amount of heat absorbed by water is 2604.54 J.
Explanation:
Amount of heat absorbed by water = 
where m represents mass, C represents specific heat and
represents change in temperature.
Here
g ,
and
= (final temperature - initial temperature) = (29.5-21.2)
= 8.3
So, amount of heat heat absorbed by water
= 
= 2604.54 J
