Answer : The concentration of 
(g) in parts per million is, 8 ppm
Explanation : Given,
Mass of oxygen gas (solute) = 0.008 g
Mass of water (solvent) = 1000 g
First we have to calculate the mass of solution.
Mass of solution = Mass of solute + Mass of solvent = 0.008 + 1000 = 1000.008 g
Now we have to calculate the concentration of (g) in parts per million.
ppm : It is defined as the mass of solute present in one million 
parts by mass of the solution.
Now put all the given values in this expression, we get
Therefore, the concentration of (g) in parts per million is, 8 ppm
Answer:
In fact this should be considered more of a continuum. For example salt dissolving in water is usually considered to be a physical change, however the chemical species in salt solution (hydrated sodium and chlorine ions) are different from the species in solid salt.
