Glycerol (molar mass 92. 09 g/mol) has been suggested for use as an alternative fuel. The enthalpy of combustion, δh°comb , of glycerol is −1654 kj/mol. What mass of glycerol would need to be combusted to heat 500. 0 g of water from 20. 0°c to 100. 0°c ? (the specific heat capacity of water is 4. 184 j/(g⋅°c). Assume that all the heat released by the combustion reaction is absorbed by the water. ).
