Hey, does anyone know a simple step method on how to calculate the mass of an alcohol when in an enthalpy context. Can you please explain something simple and easy so that i can use it for similar questions please, thanks
3. Different fuels are used for different purposes.
(a) Ethanol, C2H5OH, can be used as a fuel in some camping stoves.
(i) The enthalpy of combustion of ethanol given in the data booklet is
−1367 kJ mol−1.
Using this value, calculate the mass of ethanol, in g, required to raise the
temperature of 500 g of water from 18 °C to 100 °C.
