By using the data in this question, estimate how much oxygen a person requires on average in a life time and how far a motor can go using the same amount of oxygen. the typical daily food requirement of a person can be considered to be 1.2 kg of carbohydrate. The person obtains energy by the oxidation of the carbohydrate, which can be represented by the formula (CH2O)n.

a) Construct an equation for the complete combustion of the carbohydrate formula (CH2O)n.

b)The empirical relative formula mass of the carbohydrate is 30. Use your equation above to calculate the number of moles of oxygen required by the person each day.
