Question

Hello! When excess zinc is added to 3 mL of .25 mol/L aqueous copper2 sulfate, the calorimeter warms by 12.5 'C. What is themolar enthalpy of the aqueous copper 2 ions? - I am not sure what to do about the .25 mol/L. And Ithink we assume the specific heat capacity for water... But I amlost on everything else!

Explanation / Answer

Since zinc is in excess, copper sulfate is the limitingreagent.

3 mL of 0.25 M solution. { mol/ L means molarity}
