Question

A dilute solution of co2 in water contains 0.000540 g of co2 per 500.0 g of solution. What is the concentration of co2 in ppb?

Answer 1

1080 ppb

Step-by-step explanation:

Parts Per Billion is defined as the number of parts of a solute per one billion parts of a solution.

ppb = (Weight of Solute / Weight of Solution) × 10⁹

Data Given;

Weight of Solute (CO₂) = 0.000540 g

Weight of Solution = 500 g

Putting Values,

ppb = (0.000540 g / 500 g) × 10⁹

ppb = 1.08 × 10⁻⁶ × 10⁹

ppb = 1080

Result:

It means if given solution is containing 1 billion particles then 1080 particles in that are of CO₂.
