A person takes 15 breaths per minute. The volume of air inhaled in each breath is 448 ml and contains 21% of oxygen by volume. The exhaled air contains 16% of oxygen by volume. If all the oxygen is used in the combustion of sucrose, how much of the Sucrose is burnt in the body per day & how much heat is evolved. `Delta H_(com)` of sucrose is `= 6000 kJ mol^(-1)`. Take temperature to be 300 K throughout. [Assuming `V_("inhaled air") = V_("exhalded air"), P_(atm) = 1atm`]
