The actual ratio of the volume of carbon dioxide eliminated to the volume of oxygen consumed during the act of cellular respiration is called the respiratory quotient. It is denoted by RQ.
RQ = Amount of carbon dioxide released/Amount of oxygen absorbed
Respiratory quotient of Tripalmitin = 0.73
Amount of CO2 released = 126
Amount of oxygen consumed = 126/0.73
Amount of oxygen consumed = 172.60.
