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

  • chemistry - ,

    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
