A 6.60 g sample of solid KCl was dissolved in 47.6 g of water. The initial temperature of the water was 20.00°C. After the compo
nexus9112 [7]

Answer : The heat absorbed by the process is 1792.4 J

Explanation :

In this problem we are given that heat was completely absorbed from the water and no heat was absorbed by the reaction container or the surroundings.

q_{absorbed}=-q_{lost}

q_{lost}=-m\times c\times (T_2-T_1)

where,

q_{lost} = heat lost by the water = ?

c = specific heat of water = 4.184J/g^oC

m = mass of water = 47.6 g

T_1 = initial temperature of water = 20.00^oC

T_2 = final temperature of water = 11.00^oC

Now put all the given values in the above formula, we get

q_{lost}=-47.6g\times 4.184J/g^oC\times (11.00-20.00)^oC

q_{lost}=-1792.4J

As,

q_{absorbed}=-q_{lost}

So,

q_{absorbed}=1792.4J

Therefore, the heat absorbed by the process is 1792.4 J
