What is the final temperature of the solution formed when 0.75 grams of kmno4 is added to 85.5 grams of water at 13.2 degrees celsius in a calorimeter

is the final temperature of the given solution.

Explanation:

When heat is absorbed during reaction enthalpy is positive. To calculate amount of heat absorbed by solution:

To calculate no of moles of molar mass is 158.034 g/mol:

Hence quantity of heat can be calculated as given:

As considered that heat capacity of pure water is same as of solution (means to heat 1 gm of water by 1 degree Celsius the energy required) =

Now it is considered that due to dissolvation, no heat loss occurs and final temperature can be calculated by using specific heat capacity:

The final temperature of the solution is .

it is stable as it is in group 0 which have full outer shells of electrons
