The metabolism of glucose, C 5 H 12 O 5 yields C O 2 ( g ) and H 2 O ( I ) as products. Heat released in the process is converted to useful work with about 70% efficiency. Calculate the mass of glucose metabolized by a 58.0 kg person in climbing a mountain with an elevation gain of 1450 m. Assume that the work performed in the climb is about four times that required to simply lift 58.0 kg by 1450 m. ( Δ r H ° o f C 5 H 12 O 5 ( s ) i s − 1273.3 k J / m o l . )
