Homework Help: chemistry - Molar enthalpy

Posted by Rose Bud on Wednesday, February 29, 2012 at 9:58pm.

When 10.0 g of KOH is added to 100.0 g water, the solution's temperature increases from (25.18 C) to (47.53 C). What is the molar enthalpy of solution for KOH?

i tryed

q=(m)x(c)x(delta T)

didn't really work. i got 22.35 J

do i use that to find the molar enthalpy if so how?
