If 410 grams of CaCl2 are dissolved in 931 grams of water, what is the percent by mass concentration of the solution? (pls show the work if possible)

I would use calorimetric to determine the specific heat and I would measure the mass of a sample. I would measure the mass of a sample of the substance. I would heat the substance to a known temperature. I would place the heated substance into a coffee-cup calorimeter containing a known mass of water with a known initial temperature. I would wait for the temperature to equilibrate, then calculate temperature change. I would use the temperature change of water to determine the amount of energy absorbed. I would use the amount of energy lost by substance, mass, and temperature change to calculate specific heat.
