Enthalpy

Quick enthalpy question...

When 50 ml of .1 M AgNO3 and 50 ml of .1 ml HCl are mixed in a constant pressure calorimeter, the temperature of the mixture increases from 22.2 degrees Celsius to 23.11 degrees Celsius. The temperature increase is caused by:
AgNO3 + HCl --> AgCl + HNO3

Calculate delta H for this reaction in Kj/mole AgNO3 assuming that the combined solution has a mass of 100 grams and a specific heat of 4.18 j/g-C

Thanks!

.use ΔH=mc..Δt. get the total mass from the molarity and volume. thne plug in.

yeah, i used that but i kept getting a different answer from the book. what'd you get?

Make sure that you have the same notations. e.g. KJ and J. Dont use J with KJ make sure u convert everthting to the proper notation.
