When [sltM] g MgCl2 is dissоlved in enоugh wаter tо give [solutM] g of the solution in а coffee-cup cаlorimeter, the temperature increases from [Tlow] °C to [Thigh] °C. If the solution has a specific heat capacity which is essentially the same as water, 4.184 J/g∙ °C, calculate the enthalpy change in J per gram of MgCl2 dissolved. round your answer up to an integer number
