A 87.2 g piece of iron (s =.44 J/gC) at 120.5 C was dropped into 127 mL of
octane at 35.5 C in a coffee cup calorimeter. The final temperature reached
was 82.2 C. What is the specific heat of octane in cal/gC if the density of
octane is .703 g/mL and the calorimeter absorbs a negligible amount of
heat.?

Answer rating: 100% (QA)

First we need to calculate the heat lost by the iron when it cools down from 1205C to the final temp... View the full answer
