Glucose reacts with oxygen do produce carbon dioxide and water:
Given a daily mass of glucose:
Find moles of glucose:
From stoichiometry of this equation, moles of carbon dioxide can be found by multiplying this amount by 6:
Convert this into mass using the molar mass of carbon dioxide:
This is the mass of carbon dioxide per person per day. Multiply by the population and by the number of days to get the total mass:
H. using a pulley system can reduce the load force, over a greater distance.<span />
