The answer for this question is ΔHrxn=-441.40174468085 kJ/mol but I don't know how to arrive to that answer. 0.47g of magnesium reacts with 100ml of 1.00 mol/L HCl in the following reaction: Mg(s)+2HCl(aq)-->MgCl2(aq)+H2(g). The heat of reaction is -8537.4J Determine ΔHrxn.

Determine which is the limiting reactant, convert to moles. Multiply the moles by the The heat of reaction is -8537.4 J/mol taking into account the stoichiometry.

OpenStudy (aaronq):

by the way, i assumed this "-8537.4J" was per mole, but you didn't write it.
