5.92(g) of hydrated Feso4 when heated to a constant mass gave 3.24(g) of anhydrous salt. Calculate the number if moles off water crystallization in the hydrated salt (H=1, O=16, S=32, Fe=52)
During an experiment to find the enthalpy change for the reaction between zinc and copper sulfate solution a student recorded the temperature of the copper sulfate solution for two minutes. She then added the zinc and continued to record the temperature whilst stirring the solution in the 'coffee cup' calorimeter. She plotted a graph of her data. What value should she use for ΔT when calculating her result?
