If we really want to get down to brass tacks, eating something with a mass of 1 g increases the body mass by 1 g. Eating something with a mass of 10 g increases the body mass by 10 g (perhaps not permanently but shortly after eating). And I don't need dimensional analysis to tell me that. So I would say eating a cooking with a mass of 15.21 g will increase the body mass by 15.21 g. The only other option I see is for you to consider the cookie as 100% sucrose, look up or calculate the energy/mole, convert to 15.21 g sucrose and then to kJ and grams. Since this is a bonus question, could this be a case of the kJ energy etc being a red herring?
once i have the amount of mols of sucrose present how do i convert that to sucrose? and to kj and grams?

lets say i have 0.03110 mols of sucrose
