a human being requires 2700Kcal of energy per day.if the enthalpy of combustion of glucose is -1350Kcal/mol.how many grams of glucose a person has to consume everyday?
It will be 360 gram
the answer is 360 g
n=2700/1350=2 mol
n=given mass/molar mass hence molar mass of c6h12o6=180 g/mol
let molar mass of c6h12o6=Mm
given mass=n*Mm
=2*180 g
=360 g
