# 2% of 100L in units of mg/L?

What is 2% of 100L in units of mg/L? Step by step would help clear up my confusion.

100L of wastewater

The production of BOD_5 is approximately 2% of the mass of the feedstock, which in this case is the wastewater.

_Assuming_ that BOD_5, whatever it is, has a density reasonably close to 1, then 2% of 100 l is 2 l, or 2 kg.

mg/l already is a unit of ratio, so 2% of something with a density of 1 is 20 grams/l, or 20,000 mg/l. The volume of the base material doesn't enter that equation. Unless you've left out quite a bit.

The concentration of BOD is

2% of 1kg is 20g, 1kg is approximately 1L, so 20g/L

Need more context to answer your question, 2% of 100L is 2L but mg/L is used to measure mass of solids per liter.

2% of what? 2% of 100L is just 2 L , so I assume you are asking about something in the wastewater.
