AS level chemistry enthalpy questionWatch
In an experiment 0.16g of methanol is burnt CH3OH to heat a 100g of water from 17 to 24 celcius. Calculate the enthalpy change for the combustion of methanol?
the answer should be: -585KJmol-1
what I have done so far:
Energy transferred = 100gx 4.18x-7=-2926J=-2.296KJ
moles of fuel burnt=0.16/32= 0.005
Enthalpy change for combustion= -2.296/0.005=-459.2
why is this not right?? please explain
