Answer:
grams per liter ≈ g/L
Explanation:
The standard unit of measurement otherwise referred to as SI unit is used in describing various measurement or quantity of value.
However, Density, which is a term that describes the measurement of a substance mass per volume. It is measured using grams per cubic centimeter ≈ g/cm3 when it comes to solids and liquids densities and grams per liter ≈ g/L for gases.
Hence, in this case, since the substance of measurement is atmosphere and it is gaseous in nature, then the correct answer is grams per liter ≈ g/L.
