anonymous · Answer

@Callisto do you know?

callisto · Answer

Do you need the numerical answer or the formula to calculate it?

anonymous · Answer

the numerical answer

anonymous · Answer

But i dont know how to even get it... Im confused:(

callisto · Answer

enthalpy change = mcΔT
                           = (mass of NaOH + mass of HCl) x specific heat capacity of the solution x temperature change.

anonymous · Answer

how would i get the specific heat capacity?

callisto · Answer

Isn't it given in the question?

anonymous · Answer

i dont see it...

anonymous · Answer

well thanks though, you really did help

callisto · Answer

Alright, take an assumption then~
Assume specific heat capacity of the solution is similar to that of water, that is  = 4.186 joule/gram °C
