Thermodynamics+Test

Hey Just wondering if anyone can tell me how to convert molar heat capacity into specific heat capacity? I am not completely sure but you basically multiply the specific heat capacity into the molar mass of that substance... eg for the first question in the review you would do 4.18 J/g C x 18.02 g/mol = 75.3 J/mol C would be the molar heat capacity of water someone pls check if I am right!!

Yeah i am pretty sure thats right but say your givin the molar enthalpy how do you get it to specific heat? well I think you would be given other info like the mass and change in temp ..so that you can use q=mcT to get the specific heat capacity. you would basically do n(delta)H = mc(delta)T

Yeah that makes sense...is anyone posting the answers to the review package? If you have answers im gonna start a discussion in the discussion tab. Yes Jenna is going to scan the answers and post them up or email it to everyone.

For question 8a) does anyone know what it is asking? Because it gives you the delta h of the combustion reaction... Do you have to write out the formation equation of 2C2H6 and then divide the entalpy of formation by 2?

Jenna: Here are the answers..
