# How do we determine the concentratin of a substance by thermochemistry?

say for example,,

HCl,,

with NaOH,,

concentration of NaOH is 1.20 mol/dm^3

if needed--

10 cm^3 of both-- initial temperature--30 degrees C,,after adding--34 degrees C,,

20 cm^3 of both-- intial temperature--30 degrees C,,after adding--36 degrees C

30 cm^3 of both--initial temperature--30 degrees C,,after adding-- 36.5 degrees

40 cm^3 of both--initial temperature--30 degrees C,,after adding-- 37 degrees C

just wanna know whats the formula,,or if possible the answer too,,

plss help me,,

tomorro my teacher is gonna ask me,,,

this is all i can come up with.....sorry
