500 microliters (μ L) is how many milliliters (mL)? a) 50 ~mL b) 5 ~mL c) 0.5 ~mL d) 0.05 ~mL
The Correct Answer and Explanation is :
To convert microliters (μL) to milliliters (mL), you can use the following relationship:
1 mL = 1,000 μL.
Given this relationship, we can set up a conversion for 500 μL:
[
500 \, \text{μL} = \frac{500 \, \text{μL}}{1,000 \, \text{μL/mL}} = 0.5 \, \text{mL}.
]
Thus, the correct answer is c) 0.5 mL.
Explanation of Conversion
- Understanding the Units:
- Microliter (μL): This is a metric unit of volume equal to one-millionth of a liter (1 μL = 0.000001 L).
- Milliliter (mL): This unit is also a metric measure, equal to one-thousandth of a liter (1 mL = 0.001 L).
- Relationship Between the Units:
- Since 1 mL equals 1,000 μL, this means that microliters are a smaller unit compared to milliliters. Thus, when converting from μL to mL, you divide by 1,000.
- Conversion Process:
- To convert 500 μL to mL, divide 500 by 1,000:
[
\text{Conversion} = \frac{500}{1,000} = 0.5 \, \text{mL}.
] - This straightforward division demonstrates how many milliliters are represented by the given microliter amount.
- Practical Applications:
- This conversion is crucial in fields such as medicine, biology, and chemistry, where precise measurements of liquids are essential for experiments, treatments, and formulations. Knowing how to convert between these units can help professionals accurately dose medications or prepare solutions.
In summary, when converting microliters to milliliters, it is important to remember that 1 mL is equal to 1,000 μL, allowing for easy calculations and conversions between these two common units of volume.
