From the calculation, the concentration in parts per billion is 6 ppb.

<h3>What is ppb?</h3>

The term ppb refers to the concentration of a substance in parts per billion. We obtain the ppb using the formula;

Mass of solute/ Mass of solution * 10^9

Now, 1L = 1000cm^3 = 1000 g

The concertation in ppb = 6 * 10^-6 g/1000 g * 10^9

= 6 ppb
