The concentration of oxygen, O2, dissolved in a sample of seawater is 6.22 ppm by mass (concentration 1 ppm - 1 part per million - means 1 g of a substance in 106 g or 1 million g of seawater), and the density of seawater is 1.03 g cm-3. What is the mass, and the volume, of this seawater that contains 1.00 g of oxygen?
