1 under normal physiological assumptions one human, Ask an Expert

Academics

1. Under normal physiological assumptions, one human exhalation contains 5.1 x 10-2 g of carbon dioxide. Assuming 15 breaths per minute per person and a world population of 6.0 x 109 persons, what is the total amount of carbon dioxide released by human respiration in the course
of one year?

2. Glucose oxidation in the human body releases 6 mol of carbon dioxide per mole of glucose. How many moles of glucose are required to produce the amount of carbon dioxide?

3. Glucose oxidation has a standard enthalpy of -2803 kJ mol-1. What is the total heat produced by human respiration over the course of one year?
