Final answer:
The student's question involves converting 0.020 liters into other units of volume. The correct answer is 20 milliliters (20 mL), which is option d) among the choices provided.
Step-by-step explanation:
The question deals with converting a volume measurement from liters to other units. To find which of the provided options equates to 0.020 liters, we can look at the conversions between different volume measurements. 1 liter is equivalent to 1,000 milliliters (mL), meaning that to convert from liters to milliliters, we multiply by 1,000. Therefore, 0.020 liters is equal to 0.020 × 1,000 milliliters, which gives us 20 milliliters (20 mL).
For the other units provided: 1 centiliter (cL) is 10 milliliters, so 20 cL is 200 mL, which is not the same as 0.020 L. Similarly, 1 deciliter (dL) is 100 milliliters, so 2 dL would be 200 mL, which again is not the same as 0.020 L. Therefore, the correct answer is 20 mL, which corresponds to option d) in the question's choices.
