Asked by Raj

In a thermochemistry experiment the reaction of 0.0857 g of an unknown metal and an excess of 4.0 M HCl resulted in a 0.210 mL decrease in the volume of an ice/water mixture. Calculate the enthalpy of this reaction per 1 g of metal reacted. Needed data:
density of water at 273 K = 1.00 g/ml
density of ice at this temperature = 0.917 g/mL
ice enthalpy of fusion = 333 J/g
