If a filter gained 6 µg and the sampled volume was 3 m³, what is PM concentration?

Explanation:
Concentration is mass per unit volume. For PM, divide the mass collected on the filter by the air volume sampled. Here, 6 µg divided by 3 m³ equals 2 µg/m³. The other numbers would come from different sampled volumes (a larger volume gives a smaller concentration, a smaller volume gives a larger concentration).
