Question

If 7.400 g of C6H6 is burned and the heat produced from the burning is added to 5691 g of water at 21 °C, what is the final temperature of the water?

Answer 1

the kj to the c6h6 is 6542 and there are 2 moles it as well. For some reason i can't seem to get the right number.

Answer 2

you have to use: \(q=m*C_p*\Delta T\)

don't forget that \(\Delta T =T_f-T_i\)

so the equation is: \(q=m*C_p*(T_f-T_i)\)

Answer 3

you're a really helpful, but im just an idiot and used the wrong molar mass by accident.

Answer 4

haha ah damn
