A 55.0g sample of impure zinc reacts with exactly 129 ml of hydrochloric acid. The hydrochloric acid has a density of 1.18 g/ml and contains 35.0% HCl by mass. What is the percent of the metallic zinc in the original sample. Assume that the impurity in the zinc does not affect the HCl.

Zinc metal reacts with hydrochloric acid according to thefollowing balanced equation.

Zn(s)+2HCl(aq)?ZnCl2(aq)+H2(g)

When 0.117g of Zn(s) is combined with enough HCl to make 52.7mLof solution in a coffee-cup calorimeter, all of the zinc reacts,raising the temperature of the solution from 22.5?C to 24.6?C.

Find ?Hrxn for this reaction as written. (Use 1.0 g/mLfor the density of the solution and 4.18 J/g??C as the specificheat capacity.) Express answer in kJ/mol.
