Assume that an exhaled breath of air consists of 74.9 % N2, 15.2 % O2, 3.9 % CO2, and 6.0 %water vapor.

1) If the total pressure of the gases is 0.990 atm , calculate the partial pressure of N2. Express your answer using three significant figures.

2) If the total pressure of the gases is 0.990 atm , calculate the partial pressure of O2. Express your answer using three significant figures.

3) If the total pressure of the gases is 0.990 atm , calculate the partial pressure of CO2. Express your answer using two significant figures.

4) If the total pressure of the gases is 0.990 atm , calculate the partial pressure of water vapor. Express your answer using two significant figures.

5) If the volume of the exhaled gas is 465 mL and its temperature is 37 ∘C, calculate the number of moles of CO2 exhaled. Express your answer using two significant figures.

6) How many grams of glucose (C6H12O6) would need to be metabolized to produce this quantity of CO2? (The chemical reaction is the same as that for combustion of C6H12O6. See Section 3.2. in the textbook.) Express your answer using two significant figures.
