Answer :

To convert from kilograms per cubic meter (kg/m³) to grams per liter (g/L), you can use the fact that the two units are equivalent because of the following conversions:

1. 1 kilogram (kg) is equal to 1000 grams (g).
2. 1 cubic meter (m³) is equal to 1000 liters (L).

This makes the conversion from kg/m³ to g/L a direct one-to-one conversion without needing to adjust for any volume or mass differences, because:

- In both kg/m³ and g/L, we are converting 1 kg to 1000 g and 1 m³ to 1000 L, which cancel each other out.

Therefore, with these conversions, we can directly state:

- 1 kg/m³ is equal to 1 g/L

Now, let's apply this to the given value:

- We have 1.55 kg/m³ and since 1 kg/m³ is equal to 1 g/L, we can directly convert this to 1.55 g/L.

So, 1.55 kg/m³ is equivalent to 1.55 g/L.
