Question
What is the mass of the water used?
What is the total mass of the solution? (water+salt)
What is the temperature change of the solution? Remember to use the correct sign of delta T. A temperature increase is positive. A temperature decrease is negative.
Calculate the energy absorbed or released by the solution using the temperature change calculated. Use the mass of water plus solid. Assume the same specific heat as water (4.18J/gC). Use the correct sign for q (same sign as the temperature change).
Using the answer above and the mass of unknown, calculate the enthalpy of solution per gram for the unknown? Be sure to use the correct sign.
