You dilute a 1 mL solution of a compound to 5 mL and find that the final concentration is 400 µg/mL. What was the original concentration?
Mateo AguilarOriginal concentration = 2 mg/mL.
If the diluted sample has a concentration of 400 µg/mL, the undiluted sample had a concentration of five times that:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
