4685 kJ/mol x (1.035g/molar mass) = ? and convert to J.
q joules = Ccal x (Tfinal-Tinitial)
Solve for Tf. I would put Ccal in J.
Phthalates used as plasticizers in rubber and plastic products are believed to act as hormone mimics in human. The value of deltaHcombustion for dimethylphthalate (C10H10O4) is 4685 kJ/mol. Assume 1.035 g of dimethylphthalate is combusted in a calorimeter whose heat capacity (C calorimeter) is 7.293 kJ/Celsius at 20.142 Celsius. What is the final temperature of the calorimeter?

How do you convert 4848.975 to J?
kJ x 1000 = J.
But where did you get 4868.97...?
4685 x (1.035/197...) isn't anywhere near that number. I think you did not divide by the molar mass of the phthalate.

Ok, yeah I somehow read that as a label not as part of the equation, so
4685*(1.035/194.21)= 24.97
24.97*1000=24967.69
So then would the final equation be:
24967.69=7.293(Tfinal-20.142)
Thank you by the way Im just really struggling with this.

Yes except you need to convert that 7.293 kJ to J.
Ok I got the answer!! Thank you!!
