Imagine that you dissolve 10.0g of a mixture of NaNO3 and KF in 100.0g of water and find that the temperature rises by 2.00 degrees C.
Using the following data, calculate the mass of each compound in the original mixture.
Assume that the specific heat of the solution is 4.18 J/g C.
NaNo3 (s)--->NaNO3(aq) Delta H = +20.5 kJ/molKF(s)---> KF(aq) Delta H = -17.7 kJ/mol.
