To find the number of oxygen molecules in a person's lungs, we can follow these steps: ### Step 1: Convert the volume from liters to cubic meters The volume of air in the lungs is given as 6.0 L. We need to convert this to cubic meters (m³) because the SI unit for volume is cubic meters. \[ V = 6.0 \, \text{L} = 6.0 \times 10^{-3} \, \text{m}^3 \] ...
