If you were to measure out \( \frac{1}{1,000,000} \) of a liter, how would you express and abbreviate this volume measurement?

A. Deciliter (L)
B. Milliliter (L)
C. Milliliter (mL)
D. Microliter (L)
E. Microliter (mL)
F. Deciliter (dL)

Answer :

To express and abbreviate 1/1,000,000 of a liter, follow these steps:

1. Understanding the Fraction:
- You are measuring 1/1,000,000 of a liter. This means you are dividing one liter into one million equal parts and taking just one of those parts.

2. Unit for 1/1,000,000 of a Liter:
- The metric unit for 1/1,000,000 of a liter is called a "microliter."
- A microliter is a very small volume measurement, suitable for tiny quantities.

3. Abbreviation for Microliter:
- The abbreviation for microliter is "µL." The "µ" represents "micro," indicating the division of scale to a millionth.

Therefore, when you measure 1/1,000,000 of a liter, it is expressed and abbreviated as "1 microliter" or "1 µL."
