10.57 The metabolic oxidation of glucose, C6H1206, in our bodiesproduces CO2, which is expelled from our lungs as a gas:COH12O6(aq) + 6 O2(g) 6 CO2(g) + 6 H20(1)(a) Calculate the volume of dry CO2 produced at bodytemperature (37 °C) and 0.970 atm when 24.5 g of glucoseis consumed in this reaction. (b) Calculate the volume ofOxygen you would need, at 1.00 atm and 298 K, to completelyoxidize 50.0 g of glucose.

Given,T = 37 oC + 273.15 K= 310.15 KMolecular mass of glucose is 180.156 g/mol.
