25 mL is equivalent to how many liters (L)? Select one: O a. 0.025 L O b. 0.25 L O c. 0.0025 L O d. 2.5 L
The Correct Answer and Explanation is:
The correct answer is: a. 0.025 L
Explanation
To convert milliliters (mL) to liters (L), we need to understand the metric relationship between these two units of volume. In the metric system:
1 liter (L) = 1000 milliliters (mL)
This means that to convert milliliters to liters, we divide the number of milliliters by 1000.
Let’s apply this to the question: 25 mL÷1000=0.025 L25 \, \text{mL} \div 1000 = 0.025 \, \text{L}
So, 25 mL is equal to 0.025 liters.
Let’s briefly analyze the other answer choices to understand why they are incorrect:
- b. 0.25 L: This would be correct if the original amount was 250 mL, not 25 mL. So this value is ten times too large.
- c. 0.0025 L: This value is incorrect because it results from mistakenly dividing 25 mL by 10,000, not 1,000. It’s ten times too small.
- d. 2.5 L: This would be the conversion for 2,500 mL, which is one hundred times the original value, so it is significantly too large.
Understanding these basic conversions is important in everyday contexts, such as in cooking, science labs, and medicine, where accurate volume measurement is crucial. For example, if a doctor prescribes 25 mL of a liquid medicine, and it’s mistakenly interpreted as 2.5 L, it could lead to a dangerous overdose. Similarly, in scientific experiments, a small miscalculation in volume can result in failed results.
Therefore, always remember: Volume in Liters=Volume in Milliliters1000\text{Volume in Liters} = \frac{\text{Volume in Milliliters}}{1000}
And for this specific case: 25 mL=0.025 L25 \, \text{mL} = 0.025 \, \text{L}
Correct answer: a. 0.025 L ✅
