The sugar C6H1206 has a Hcombustion 2801 kJ Gasoline has a h

The sugar, C6H1206, has a Hcombustion _-2801 kJ Gasoline has a heat of combustion reported as -34 kJ/g Which material provides more energy per gram? Solution: FW of CsH1206-180 g mol-1 Gasoline is a complex mixture of hydrocarbons with C5 to C10

Solution

Molar mass of Sugar = 180 gm/mol

Let us convert the heat of combuston per gram of glucose

Heat of combustion = -2801 / 180 = 15.56 Kj / gm

Heat of combustion of gasoline = -34 Kj/ gm

Hence among them Gasoline is will produce more energy than Glucose
