When glucose, C6H12O6, is oxidized in our bodies energy is produced. In addition,CO2, is produced as a gas. The carbon dioxide gas eventualy finds its way from the cells to the lungs where it is expelled from the body. C6H12O6(aq) + 6 O2(g) → 6 CO2(g) + 6 H2O(l) + ENERGY Calculate the volume of dry CO2 produced at body temperature (37°C) and 0.980 atm when 23.1 g of glucose is consumed in this reaction. ________L Give the answer again with the correct number of significnt figures. _________ L
C6H12O6(aq) + 6 O2(g) → 6 CO2(g) + 6 H2O(l) + ENERGY
no of mol of glucose reacted = w/mwt = 23.1/180 = 0.1283 mole
no of mole of CO2 produced = 6*0.1283 = 0.7698 mol
volume of CO2 produced = nRT/P
= 0.7698*0.0821*310 / 0.98
= 19.99 L
volume of CO2 with correct number of significnt figures = 20 L
