When 5 grams of salt is dissolved in 95 grams of water the temperature of the solution increases 10°C how much heat is evolved the heat capacity of the solution is 1.1 cal/g°C

Total mass of solution = 5 + 95 = 100 grams
Recall that the formula for calculating the heat absorbed or released is given by
Q = mc(T2  T1)
where
m = mass
c = specific heat capacity
(T2  T1) = change in Temperature
Substituting,
Q = 100 * 1.1 * 10
Q = 1100 cal
Hope this helps :3
