How Much Glucose Does a Person Metabolize Climbing a Mountain?

[n.a.s.h]

Homework Statement

The metabolism of glucose, C6H12O6, yields Co2(g) and H2O(l) as products. Heat released in the process is converted to useful work with about 70% efficiency.

Calculate the mass of glucose metabolized by a 59.0-kg person in climbing a mountain with an elevation gain of 1550m . Assume that the work performed in the climb is about four times that required to simply lift 59.0 kg by 1550m .

Homework Equations

(enthalpy of formation of C6H12O6(s) is -1273.3 kJ/mol.)

The Attempt at a Solution

Im so confused with this question and i do not even know where to start...Any help will be appreciated...

Start calculating amount of work done by climber. This is simple physics.
