Therefore, wadd,max = −2888 kJ for the combustion of 1 mol glucose molecules, and
the reaction can be used to do up to 2888 kJ of non-expansion work. To place this
result in perspective, consider that a person of mass 70 kg needs to do 2.1 kJ of work
to climb vertically through 3.0 m; therefore, at least 0.13 g of glucose is needed to
complete the task (and in practice significantly more).
