Assignment:
Show that an SO2 atmospheric concentration of 0.2 ppb(v) is equivalent to 0.4 ppb(w) stands for weight and ppb(w) refers to the number of tonnes (or grams) of SO2 in 10^9 tonnes (or grams) of air.
The (v) of ppb (v) stands for volume.
The ppb stands for parts per billion.
Every unit volume of atmospheric air contains (on average) 0.2 x 10^-9 units volume of Sulfur Dioxide.
Provide complete and step by step solution for the question and show calculations and use formulas.
